- 4. Quantum Technology Quantum technology is an emerging field of physics and engineering, which relies on the principles of quantum physics. It is a technology that works by using the principles of quantum mechanics (the physics of sub-atomic particles), including quantum entanglement and quantum superposition. Quantum technology is based on the ability to precisely control individual quantum systems in order to make use of the phenomena described above.
- 6. Quantum Computing Quantum computing is the use of quantum phenomena such as superposition and entanglement to perform computation. Computers that perform quantum computations are known as quantum computers. Quantum computing began in the early 1980s, when physicist Paul Benioff proposed a quantum mechanical model of the Turing machine. There are several models of quantum computing, including the quantum circuit model, quantum Turing machine, adiabatic quantum computer, one-way quantum computer, and various quantum cellular automata. The most widely used model is the quantum circuit.
- 7. Quantum Computers ◦ A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. ◦ Computers that perform quantum computations are known as quantum computers. ◦ Quantum computer employs quantum bits, or qubits, that can be both 0 and 1 at the same time. ◦ Quantum computers are believed to be able to solve certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers.
- 9. Qubits ◦ Quantum computers aren't limited to two states; they encode information as quantum bits, or qubits, which can exist in superposition. ◦ In quantum computing, a qubit or quantum bit is the basic unit of quantum information. ◦ In a classical system, a bit would have to be in one state or the other. However, quantum mechanics allows the qubit to be in a coherent superposition of both states simultaneously, a property which is fundamental to quantum mechanics and quantum computing.
- 11. What makes a Quantum Computer different from a conventional computer? Quantum computers can solve problems that are impossible or would take a traditional computer an impractical amount of time (a billion years) to solve. Virtually unbreakable encryption? Quantum computers will change the landscape of data security. Even though quantum computers would be able to crack many of today’s encryption techniques, predictions are that they would create hack-proof replacements. Classical computers are better at some tasks than quantum computers (email, spreadsheets and desktop publishing to name a few). The intent of quantum computers is to be a different tool to solve different problems, not to replace classical computers.
- 12. What makes a Quantum Computer different from a conventional computer? Quantum computers are great for solving optimization problems from figuring out the best way to schedule flights at an airport to determining the best delivery routes for the FedEx truck. Google announced it has a quantum computer that is 100 million times faster than any classical computer in its lab. Every day, we produce 2.5 exabytes of data. That number is equivalent to the content on 5 million laptops. Quantum computers will make it possible to process the amount of data we’re generating in the age of big data. According to Professor Catherine McGeoch at Amherst University, a quantum computer is “thousands of times” faster than a conventional computer.
- 13. What makes a Quantum Computer different from a conventional computer? Superposition is the term used to describe the quantum state where particles can exist in multiple states at the same time, and which allows quantum computers to look at many different variables at the same time. Rather than use more electricity, quantum computers will reduce power consumption anywhere from 100 up to 1000 times because quantum computers use quantum tunneling. There are several algorithms already developed for quantum computers including Grover’s for searching an unstructured database and Shor’s for factoring large numbers.
- 14. What makes a Quantum Computer different from a conventional computer? Once a stable quantum computer gets developed, expect that machine learning will exponentially accelerate even reducing the time to solve a problem from hundreds of thousands of years to seconds. Remember when IBM’s computer Deep Blue defeated chess champion, Garry Kasparov in 1997? It was able to gain a competitive advantage because it examined 200 million possible moves each second. A quantum machine would be able to calculate 1 trillion moves per second!
- 15. Do Quantum Computers really exists? The world's biggest tech companies are jockeying for quantum supremacy. IBM and Google are racing to create a truly useful quantum computer. Here's what makes quantum computers different from normal computers and how they could change the world. Google and IBM are both working to do that. IBM uses a technique where it drops superconducting circuits into a sub-zero refrigerator, a delicate process that requires extreme care. That's why the computers it will offer up to other businesses will remain in IBM facilities in New York as customers access them over the internet. Google researchers say the company has a similar plan to offer access to its quantum processors via the cloud, building on work that grew out of the University of California, Santa Barbara.
- 16. Do Quantum Computers really exists? Recently, Google claimed that it had achieved quantum supremacy – the first time a quantum computer has outperformed a traditional one. You’ll probably never have a quantum chip in your laptop or smartphone. There’s not going to be an iPhone Q. Quantum computers have been theorized about for decades, but the reason it’s taken so long for them to arrive is that they’re incredibly sensitive to interference. Quantum computing could change the world – but right now, its future remains uncertain. Researchers have made great progress in developing the algorithms that quantum computers will use. But the devices themselves still need a lot more work.

- 18. How can you learn Quantum Computing? Right now, the best quantum computers have about 50 qubits. That’s enough to make them incredibly powerful, because every qubit you add means an exponential increase in processing capacity. But they also have really high error rates. It’s already possible to use IBM’s quantum computer via its website. You can even play a card game with it. Here you can access Quantum Computer.
