Quantum Computing: Principles and Applications

The development of quantum computers over the past few years is probably one of the significant advancements in the history of quantum computing. D-Wave quantum computer has been available for more than eight years. IBM has made its quantum...

Quantum Computing Review: A Decade of Research

Quantum computing (QC) has the potential to be the next abstruse technology, with a wide range of possible applications and ramifications for organizations and markets. QC provides an exponential speedup by employing quantum mechanics princ...

A manufacturable platform for photonic quantum computing

Abstract Although holding great promise for low noise, ease of operation and networking 1 , useful photonic quantum computing has been precluded by the need for beyond-state-of-the-art components, manufactured by the millions 2–6 . Here we ...

Automata and quantum computing

Quantum computing is a new model of computation, based on quantum physics. Quantum computers can be exponentially faster than conventional computers for problems such as factoring. Besides full-scale quantum computers, more restricted model...

Quantum computing with neutral atoms

With their hyperfine states serving as two-level qubits, atoms can be packed into closely spaced, laser-cooled arrays and be individually addressed using laser pulses....

Quantum Computing with an Electron Spin Ensemble

We propose to encode a register of quantum bits in different collective electron spin wave excitations in a solid medium. Coupling to spins is enabled by locating them in the vicinity of a superconducting transmission line cavity, and makin...

Quantum computing. I

Quantum computers will be useful for all kinds of computing. In addition to computer graphics they will have applications in cryptography, biology, and communications. We start with a look at the general principles of quantum mechanics as t...
