The Schrödinger Equation Gets Practical: Quantum Algorithm Speeds Up Real-World Simulations Quantum computing has taken a major leap forward with a new algorithm designed to simulate coupled harmonic oscillators, systems that model everything from molecular vibrations to bridges and neural networks. By reformulating the dynamics of these oscillators into the Schrödinger equation and applying Hamiltonian simulation methods, researchers have shown that complex physical systems can be simulated exponentially faster on a quantum computer than with traditional algorithms.

The last two days have seen two extremely interesting breakthroughs announced in quantum computing. There is a long path ahead, but these both point to the potential for dramatically upscaling ambitions for what's possible in relatively short timeframes. The most prominent advance was Microsoft's announcement of Majorana 1, a chip powered by "topological qubits" using a new material. This enables hardware-protected qubits that are more stable and fault-tolerant. The chip currently contains 8 topologic qubits, but it is designed to house one million. This is many orders of dimension larger than current systems. DARPA has selected the system for its utility-scale quantum computing program. Microsoft believes they can create a fault-tolerant quantum computer prototype in years. The other breakthrough is extraordinary: quantum gate teleportation, linking two quantum processes using quantum teleportation. Instead of packing millions of qubits into a single machine—which is exceptionally challenging—this approach allows smaller quantum devices to be connected via optical fibers, working together as one system. Oxford University researchers proved that distributed quantum computing can perform powerful calculations more efficiently than classical systems. This could not only create a pathway to workable quantum computers, but also a quantum internet, enabling ultra-secure communication and advanced computational capabilities. It certainly seems that the pace of scientific progress is increasing. Some of the applications - such as in quantum computing - could have massive implications, including in turn accelerating science across domains.

A quantum computer recently solved a problem in just four minutes that would take even the most advanced classical supercomputer billions of years to complete. This breakthrough was achieved using a 76-qubit photon-based quantum computer prototype called Jiuzhang. Unlike traditional computers, which rely on electrical circuits, this quantum computer uses an intricate system of lasers, mirrors, prisms, and photon detectors to process information. It performs calculations using a technique known as Gaussian boson sampling, which detects and counts photons. With the ability to count 76 photons, this system far surpasses the five-photon limit of conventional supercomputers. Beyond being a scientific milestone, this technique has real-world potential. It could help solve highly complex problems in quantum chemistry, advanced mathematics, and even contribute to developing a large-scale quantum internet. For example, quantum computers could help scientists design new medicines by simulating how molecules interact at the quantum level—something that classical computers struggle to do efficiently. This could lead to faster discoveries of life-saving drugs and treatments. While both quantum and classical computers are used to solve problems, they function very differently. Quantum computers take advantage of the unique properties of quantum mechanics—such as superposition and entanglement—to perform calculations at incredible speeds. This makes them especially powerful for solving problems that would be nearly impossible for traditional computers, bringing exciting new possibilities for scientific and technological advancements. As the Gaelic saying goes, “Tús maith leath na hoibre”—“A good start is half the work.” Quantum computing is still in its early stages, but its potential to reshape science, medicine, and technology is already clear.

Physicists have created "hotter" Schrödinger cat states, which are quantum states that exist in multiple conditions at once, by maintaining quantum superpositions at higher temperatures than previously possible. This breakthrough, achieved at temperatures up to 1.8 Kelvin—or about 60 times hotter than the previous record—demonstrates that quantum phenomena can persist in warmer, less ideal conditions. This could significantly lower the cost and complexity of quantum technology, making quantum computers more practical and easier to build. The breakthrough What they are: A "Schrödinger cat state" is a quantum system in a superposition of two distinct states simultaneously, a concept named after the famous thought experiment. The challenge: Normally, these states are so fragile they must be maintained at temperatures near absolute zero to prevent the superposition from collapsing. The new achievement: A research team created these states at temperatures up to 1.8 Kelvin, which is much warmer than the previous limit. How they did it: They adapted experimental protocols to generate and maintain the quantum states at these higher temperatures, using a specialized microwave resonator and carefully designed microwave pulses. Significance for quantum technology Reduced costs: The ability to perform experiments at higher temperatures means less need for extremely expensive and complex cooling equipment. New possibilities: It shows that quantum interference can persist even in less-than-ideal conditions, opening new opportunities for quantum computing and other technologies. More practical quantum computers: By proving that quantum effects are more robust, this research moves quantum technology closer to practical applications that could run in less controlled environments.

Quantum Computing (QC) 1/2 What is it? Quantum machines encode data using quantum bits or #qubits that can store either a zero or a one like computers today but also a weighted combination of zero and one at the same time. Principles used include #Superposition - quantum particle can represent multiple possibilities, #Entanglement - multiple particles become correlated more strongly than regular probability allows, #Decoherence - particles decay, collapse or change converting into single states measurable by physics, and #Interference - entangled particles can interact and produce more and less likely probabilities. QC can scale exponentially - 2 qubits can compute 4 pieces of information, 3 can compute 8 etc.    Today's computer v. QC - Instead of computing every step of a complicated calculation, QC can process enormous datasets simultaneously with different operators resulting in massive scale and efficiency to solve problems. Also instead of providing a single answer which is very precise, QC provide ranges of possible answers. See image.   Use cases -  #Pharmaceuticals - Molecular formulations which are the basis of drug discovery are actually quantum systems (molecules) based on quantum physics. Exact methods are computationally intractable for today's computers and approximations are often not accurate when interactions at the atomic level are critical. So in theory, the inability of an average computer today re: the limitations of basic calculations predicting molecule behavior using tools such as molecular Dynamics or Density Function Theory could be significantly improved using QC as it can now increase the scope of biological mechanism (protein folding), shorten screening time and reduce the number of iterations that result in no significant outcome. #Cybersecurity - QC allows you to take the leap from pseudo-random number generators - limitation being you cannot really generate random encryption because of the code they are built on can never be truly random and always follows a pattern to post-quantum cryptography - where given the enormous computing power and quantum physics, quantum algorithms can truly generate random numbers. So we'll move on from symmetric (AES) and asymmetric (RSA) cryptography. But on the flip side, this computational power of QC could be enough to crack AES and RSA encryptions.  I'll share what's the hold up and future in the next post.    Further Reading -  https://lnkd.in/eUMumUgp https://lnkd.in/eTVy4DnW   #quantumcomputing  Carpe Diem
