Exploring Quantum vs Classical Mechanics on Day 3 of QuCode

Day 3 of my QuCode 21 Days Quantum Computing Challenge – Cohort 3! Today’s exploration was all about Quantum vs. Classical Mechanics, with a deep dive into the mind-bending ideas of Superposition and Wave-Particle Duality. It’s fascinating to contrast the certainty of classical physics with the probabilistic and mysterious behavior of the quantum world — where particles can be in multiple states at once, and light seamlessly switches between wave and particle depending on how we observe it. Key Insights from Day 3: ⚛️ Superposition – Qubits can hold 0 and 1 at the same time, offering exponential computational power beyond classical bits. 🌊 Wave-Particle Duality – Nature doesn’t pick one form; it adapts. A single photon can show wave-like interference or particle-like detection. 🔮 Quantum vs. Classical – The deterministic rules of Newton meet the probabilistic rules of quantum mechanics, redefining how we see reality and computation. This journey feels like more than just physics — it’s a new perspective on information, where uncertainty becomes not a limitation, but a feature to harness. Thanks to QuCode’s guidance, these complex ideas feel clear and inspiring. Can’t wait to see how this ties into classical logic gates and quantum circuits in tomorrow’s session! 🚀✨ #QuantumComputing #Day3 #QuCodeChallenge #Superposition #WaveParticleDuality #QuantumMechanics #FutureTech

🚀 Day 3 of the QuCode 21 Days Quantum Computing Challenge – #Qohort 3 Today’s theme: Quantum vs. Classical Mechanics ⚛️ 🔹 Light and matter show wave– particle duality- revealed beautifully in Young’s double-slit experiment. 🔹 Key ideas in quantum physics explored: 1️⃣ Entanglement – particles remain connected, no matter the distance. 2️⃣ Superposition – a system can exist in multiple states until observed (hello Schrödinger’s cat 🐱). 3️⃣ Uncertainty Principle – we can’t know both position and momentum with precision. 4️⃣ Quantum Tunneling – particles pass through barriers that classical physics forbids. 5️⃣ Quantum Computing – harnessing these principles with qubits to solve problems classical computers struggle with. ✨ Takeaway: Quantum mechanics challenges our classical intuition, but it’s this strangeness that powers the future of computation.

🚀 Advancing through Qucode Cohort 3, the 21-day national-level program on Quantum Computing, where we are building step by step toward Quantum Machine Learning. ✨ Day 3 Reflections: Physics — Quantum vs. Classical Mechanics Today’s focus was on the fundamental physics that distinguishes the quantum world from the classical: 🔹 Superposition — the ability of quantum systems to exist in multiple states simultaneously 🔹 Wave-particle duality — understanding how particles can behave both as discrete particles and continuous waves 🔹 Quantum vs. Classical mechanics — highlighting the conceptual shift required to think beyond deterministic classical models 💡 The key realization was how these principles form the backbone of quantum computation: without concepts like superposition, the parallelism of quantum algorithms would not be possible. 📺 Reference Material (~30–35 mins): Quantum Mechanics Introduction — Veritasium Superposition Explained — MinutePhysics Quantum vs. Classical — SandboxAQ Wave-Particle Duality — Domain of Science Additional Resource 1 Additional Resource 2 Looking forward to applying these quantum principles as we move deeper into computational frameworks. #QuantumComputing #QuantumMachineLearning #QucodeCohort3 #Superposition #WaveParticleDuality #QuantumMechanics #FutureTech

Day 03 from #QuCode Superposition allows a quantum system to exist in multiple states simultaneously until measurement fixes it to a definite outcome, while quantum entanglement binds particles together so that the state of one instantly influences the other, regardless of distance. The uncertainty principle highlights the fundamental limit of simultaneously knowing both position and momentum, and quantum tunneling reveals how particles can penetrate barriers that classical physics would forbid. These ideas underpin qubits in quantum computing, where information is encoded beyond the binary 0 and 1, supported mathematically by Schrödinger’s equation, the Hamiltonian operator, and Born’s probabilistic interpretation. Different interpretations — Copenhagen, Many Worlds, Decoherence, and Bohmian mechanics — continue to frame how these principles are understood. Having been in this field for a long time, these concepts were not entirely new to me, yet they formed the central theme of Day 3 of QuCode’s 21-Day Quantum Challenge. #21DaysQuantumChallenge #QuCode

🚀 Day 7 complete – QuCode 21 Days Quantum Computing Challenge Today’s deep dive: The Schrödinger equation – the backbone of quantum mechanics, describing how quantum states evolve with time. Measurement – unlike classical physics, we can’t pinpoint outcomes. Instead, the wave function tells us the probabilities of different results. The act of measurement itself changes the state. The postulates of quantum mechanics – from state representation to time evolution and measurement, they set the framework of the entire theory. Every day it feels clearer why quantum computing rests on these foundations it’s not just math, it’s a new way of thinking about physical reality. #Day7 #QuantumComputing #SchrodingerEquation #Measurement #QuantumMechanics #QuCode

🎯 Day 7 of QuCode 21 Days Challenge : 🔬 Today I learned about the Schrödinger Equation, the core of quantum mechanics. It describes how a quantum state changes over time. Just like Newton’s laws explain motion in classical physics, Schrödinger’s equation explains the evolution of quantum systems. 🌊 This change in states can be linked to the wave nature of particles → a quantum particle behaves like a wave, and its state evolves smoothly according to the equation. 📌 Quantum Mechanics Postulates (simplified): 1. A system is represented by a state vector |ψ⟩ in Hilbert space. 2. Observables (like position, momentum, energy) are represented by operators. 3. Measurement outcomes are eigenvalues of those operators. 4. The state evolves over time using the Schrödinger equation. 👉 In short: The Schrödinger equation is the rulebook for how quantum states evolve — the foundation of quantum computing and quantum mechanics. #21DaysChallenge #QuantumComputing #SchrodingerEquation #QuantumMechanics #QuCode

#Day2Completed #ProbabilityAndStatistics Day2 : Basic probability, Distributions, Bayes' Theorem. In the world of quantum mechanics, everything is probabilistic, that is, there is no determinism, unlike classical physics. This probabilistic nature is what makes quantum mechanics both fascinating and challenging. Therefore understanding the concepts of probability and statistics is essential to understand quantum mechanics and its application in various sectors, especially in quantum computing, which is what we addressed in today's lesson on the most important concepts of probability "Bayes Theorem" and "Decision trees" . 🌐Probability isn't just a tool here; it's the language of quantum mechanics🌐 QuCode

🔮 Day 07 of 21 – Quantum Computing Journey 🔮 Today’s focus brought me to the heart of quantum mechanics—the principles that define how quantum systems behave:QuCode ⚡ Schrödinger Equation – Often called the “equation of motion” for quantum mechanics. It governs how quantum states evolve over time, much like Newton’s laws do in classical physics. ⚡ Measurement – A fascinating concept where observing a quantum system changes it. Measurement collapses a superposition into a definite state, shaping the outcome of quantum experiments. ⚡ Postulates of Quantum Mechanics – The fundamental rules that describe quantum systems: states, observables, measurement, and evolution. These postulates form the backbone of everything we do in quantum computing. ✨ Reflection: Quantum mechanics feels paradoxical—systems evolve smoothly under the Schrödinger equation, yet behave unpredictably during measurement. Understanding this duality is key to appreciating both the power and the limits of quantum computing. Step by step, the abstract world of quantum mechanics is becoming a structured framework for building real technology. 🚀 #QuantumComputing #21DayChallenge #LearningJourney #SchrodingerEquation #QuantumMechanics #QuCode

⚛️ Day 3 of my QuCode 21 Days Quantum Computing Challenge – Cohort 3! Today’s focus was on Quantum vs. Classical Mechanics — diving into the fascinating concepts of Superposition and Wave-Particle Duality. It’s incredible to see how the deterministic world of classical mechanics contrasts with the probabilistic, almost poetic behavior of quantum systems — where a particle can exist in multiple states until measured, and light behaves as both a wave and a particle. Today's Key Takeaways ⚛️ Superposition – Unlike classical bits, which are either 0 or 1, quantum states can exist in combinations of both — unlocking the potential for massive parallelism. 🌊 Wave-Particle Duality – The dual nature of matter and light shows us that context defines behavior — a photon can be a wave in one experiment and a particle in another. 🔮 Quantum vs. Classical – While classical physics provides certainty and predictability, quantum mechanics introduces probability, uncertainty, and new dimensions of computation. This shift in perspective — from definite states to overlapping possibilities — is what makes quantum computing so transformative. It’s not just physics; it’s a new way of thinking about information itself. QuCode’s resources made these concepts vivid and intuitive, reminding me that at its core, quantum mechanics is about embracing uncertainty as a tool for innovation. Excited to see how this foundation connects to classical computing and logic gates in Day 4! 🚀✨ #QuantumComputing #Day3 #QuCodeChallenge #Superposition #WaveParticleDuality #LearningJourney #FutureOfTech
