Quantum Computing 2017 Update
Quantum computers may soon be the most powerful data center hardware. Here I review quantum computing concepts, and highlight recent innovations from IBM, D-Wave Systems, Google, Microsoft, Intel and Alibaba. You can learn more about quantum computing in my book "Digital Genesis: The Future of Computing, Robots and AI": http://www.explainingcomputers.com/genesis.html You can purchase "Digital Ge
A Startup Uses Quantum Computing to Boost Machine Learning
If it fulfills its promise, quantum machine learning could transform AI. A company in California just proved that an exotic and potentially game-changing kind of computer can be used to perform a common form of machine learning. The feat raises hopes that quantum computers, which exploit the logic-defying principles of quantum physics to perform certain types of calculations at ridiculous speeds,

Microsoft's Quantum Computing Vaporware
Last week Microsoft made press for taking a “path less traveled” to building a quantum computer. Bloomberg Tech reported that, in theory, Microsoft’s “topological” approach to quantum computing will be less error-prone than its competitors’ non-topological approaches. Like all theories, however, it remains to be seen whether a topological approach to quantum computing will actually work. For now,
An Interactive Introduction To Quantum Computing
Or What Do You Mean They Can Be Both Zero And One At The Same Time! By David Kemp @david_b_kemp This article was originally written in 2014, but has had some minor improvements in December 2017 and January 2018 when I received some useful feedback after the article had unexpectedly been posted on Hacker News in December 2017. Heard of quantum computers? Heard that they are faster than conventional
EeroQ
Quantum computers are not just advanced computers; they have the potential to revolutionize various fields. Unlike traditional computers that represent data in binary code, 0 or 1, a quantum computer can represent data as 0, 1, or a “superposition.” A superposition is a state that is neither 0 nor 1 but multiple states simultaneously. This unique capability allows a quantum computer to process inf
Quantum computing and Bitcoin - Bitcoin Wiki
Quantum computers are computers which exploit quantum mechanics to do certain computations far more quickly than traditional computers. A sufficiently large quantum computer would cause some trouble for Bitcoin, though it would certainly not be insurmountable. Note that the abbreviation QC can stand for either quantum computer(s) or quantum cryptography. QC attacks The most dangerous attack by qua

Simple is beautiful in quantum computing
Quantum computers use electron spin orientation at a defect site in diamond to store information. The electron spin can be up (+1), down (-1), or anything in between. The spin (left, red arrow) is represented as a vector on a sphere. To change the spin from Position 1 to 2 normally requires two separate optical pulses. However, here a particular single pulse has accomplished the same electronic tr
Black holes, curved spacetime and quantum computing
Black holes, curved spacetime and quantum computing by Elsevier Rotating black holes and computers that use quantum-mechanical phenomena to process information are topics that have fascinated science lovers for decades, but even the most innovative thinkers rarely put them together. Now, however, theoretical physicist Ovidiu Racorean from the General Direction of Information Technology, Bucharest,
The Quantum Sensei: Dr. Hidetoshi Nishimori Discusses Quantum Annealing
The Quantum Sensei: Dr. Hidetoshi Nishimori Discusses Quantum Annealing Dr. Hidetoshi Nishimori Answers Whurley’s Questions About Quantum AnnealingIf you’ve never heard of Hidetoshi Nishimori, then you might as well have never heard of quantum computing. His 1998 theory of quantum annealing has since been studied and tested extensively on real machines, paving the way for much of the progress in t
Energy gaps in quantum first-order mean-field-like transitions: The problems that quantum annealing cannot solve
We study first-order quantum phase transitions in models where the mean-field traitment is exact, and the exponentially fast closure of the energy gap with the system size at the transition. We consider exactly solvable ferromagnetic models, and show that they reduce to the Grover problem in a particular limit. We compute the coefficient in the exponential closure of the gap using an instantonic a
