QEC and Architecture

Dr. Simon Devitt of Turing, Inc. rejoins us to describe how error correction affects our architectural choices. The farther beyond the QEC threshold our technology is, the less error correction …

Error Propagation and Threshold

Dr. Simon Devitt of Turing, Inc. rejoins us to describe how errors propagate inside a quantum system, and how that leads us to determine a threshold for a quantum error …

History of Quantum Error Correction

In this video, Dr. Simon Devitt of Turing, Inc. joins us to talk briefly about the history of quantum error correction (QEC) from 1997 through the present. He leads us …

Quantum Computing Resources

Try Quantum Computing yourself: IBM Our biggest piece of advice, if you are interested in quantum computing, is to go try it yourself. This requires a certain amount of effort …

Conclusion

No doubt you have learned quite a bit quantum computing – why researchers and businesspeople are excited about the potential uses of quantum computers; something about the underlying science of …

Introduction of Week 4

So far, we have discussed quantum computers in rather abstract fashion. Of course, we would like to build and actually use them. Earlier, we saw how state variables represent quantum …

Study with us in Japan!

Congratulations for making it to the end of this four week course, Understanding Quantum Computers. If this online course has inspired you to take your studies further, you may be …

Venture Capital

We have discussed research supported by governments and conducted both in universities and in national labs or government institutes, and in the laboratories of several major corporate research labs, where …

Startups

Ambitious visionaries created the first startup companies in the fields of quantum computing and quantum networking in 1999. The community grew slowly at first, but since 2013 there has been …

Quantum codes

Finally, we have the tools to understand quantum error correcting codes. We know what types of errors happen, and how to measure the parity of groups of qubits without destroying …

Big company labs & development

Rather than promote a particular company, this article is intended to give you a sense of the breadth of commitment to the overall area in the traditional players in corporate …

Large Scale Quantum Computer Systems

Professor Kae Nemoto returns to describe two of the large-scale quantum computer systems she has helped design. One uses photonic chips to continuously create entangled states consisting of many photons. …

Today’s Quantum Computers

What are the capabilities of today’s systems, and how far will we get in the near future? Noisy, Intermediate-Scale Quantum (NISQ) systems are building on today’s technology. Defining a “Winning” …

Government and University Research

A lot of the work that laid the foundations for quantum information was conducted by people who considered their field to be theoretical quantum mechanics. They produced results such as …
