Optical Quantum Computing [PDF]
Science, 2007 In 2001 all-optical quantum computing became feasible with the discovery that scalable quantum computing is possible using only single photon sources, linear optical elements, and single photon detectors.

Quantum Holonomies for Quantum Computing [PDF]
International Journal of Modern Physics B, 2001 Holonomic Quantum Computation (HQC) is an all-geometrical approach to quantum information processing. In the HQC strategy information is encoded in degenerate eigen-spaces of a parametric family of Hamiltonians.

Conservative Quantum Computing [PDF]
Physical Review Letters, 2002 Conservation laws limit the accuracy of physical implementations of elementary quantum logic gates. If the computational basis is represented by a component of spin and physical implementations obey the angular momentum conservation law, any physically ...

Ergodic quantum computing [PDF]
Quantum Information Processing, 2004 We propose a (theoretical ;-) model for quantum computation where the result can be read out from the time average of the Hamiltonian dynamics of a 2-dimensional crystal on a cylinder.

American Journal of Physics, 1998 The main features of quantum computing are described in the framework of spin resonance methods. Stress is put on the fact that quantum computing is itself nothing but a reinterpretation (fruitful indeed) of well-known concepts. The role of the two basic operations, one-spin rotation and controlled-NOT gates, is analyzed, and some exercises are ...

Encoding-independent optimization problem formulation for quantum computing
Frontiers in Quantum Science and Technology, 2023 We review encoding and hardware-independent formulations of optimization problems for quantum computing. Using this generalized approach, an extensive library of optimization problems from the literature and their various derived spin encodings are ...

Nature, 2010 Over the past several decades, quantum information science has emerged to seek answers to the question: can we gain some advantage by storing, transmitting and processing information encoded in systems that exhibit unique quantum properties? Today it is understood that the answer is yes, and many research groups around the world are working towards the

Practical distributed quantum information processing with LOCCNet
npj Quantum Information, 2021 Distributed quantum information processing is essential for building quantum networks and enabling more extensive quantum computations. In this regime, several spatially separated parties share a multipartite quantum system, and the most natural set of ...

Pulse-Engineered Controlled-V Gate and Its Applications on Superconducting Quantum Device
IEEE Transactions on Quantum Engineering, 2022 In this article, we demonstrate that, by employing the OpenPulse design kit for IBM superconducting quantum devices, the controlled-V gate (cv gate) can be implemented in about half the gate time to the controlled-X gate (cx or cnot gate) and ...
