Adiabatic Quantum Computation is Equivalent to Standard Quantum Computation [PDF]
45th Annual IEEE Symposium on Foundations of Computer Science, 2004 Adiabatic quantum computation has recently attracted attention in the physics and computer science communities, but its computational power was unknown. We describe an efficient adiabatic simulation of any given quantum algorithm, which implies that the adiabatic computation model and the conventional quantum computation model are polynomially ...

Quantum Simulations on a Quantum Computer [PDF]
, 1999 We present a general scheme for performing a simulation of the dynamics of one quantum system using another. This scheme is used to experimentally simulate the dynamics of truncated quantum harmonic and anharmonic oscillators using nuclear magnetic ...

Quantum computation with quantum dots [PDF]
Physical Review A, 1998 We propose a new implementation of a universal set of one- and two-qubit gates for quantum computation using the spin states of coupled single-electron quantum dots. Desired operations are effected by the gating of the tunneling barrier between neighboring dots.

Ultrafast creation of large Schrödinger cat states of an atom
Nature Communications, 2017 Generation of mesoscopic quantum superpositions requires both reliable coherent control and isolation from the environment. Here, the authors succeed in creating a variety of cat states of a single trapped atom, mapping spin superpositions into spatial ...

Emergence of Fermi-Dirac Thermalization in the Quantum Computer Core [PDF]
, 2000 We model an isolated quantum computer as a two-dimensional lattice of qubits (spin halves) with fluctuations in individual qubit energies and residual short-range inter-qubit couplings.

Quantum Gravity on a Quantum Computer? [PDF]
Foundations of Physics, 2013 EPR-type measurements on spatially separated entangled spin qubits allow one, in principle, to detect curvature. Also the entanglement of the vacuum state is affected by curvature. Here, we ask if the curvature of spacetime can be expressed entirely in terms of the spatial entanglement structure of the vacuum.

Hybrid quantum computing with ancillas [PDF]
, 2002 In the quest to build a practical quantum computer, it is important to use efficient schemes for enacting the elementary quantum operations from which quantum computer programs are constructed. The opposing requirements of well-protected quantum data and
