Optimizing a phase gate using quantum interference.
نویسندگان
چکیده
A controlled interference is proposed to reduce, by two orders of magnitude, the decoherence of a quantum gate for which the gate fidelity is limited by coupling to states other than the /0> and /1> qubit states. This phenomenon is demonstrated in an ultracold neutral atom implementation of a phase gate using qubits based on motional states in individual wells of an optical lattice.

Coherent Control of Quantum Entropy via Quantum Interference in a Four-Level Atomic System
The time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. Quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. It is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. The phase dependence of the atom-field entanglement is...
متن کاملHigh-fidelity Universal Quantum Gates through Group-symmetrized Rapid Passage
Twisted rapid passage is a type of non-adiabatic rapid passage that generates controllable quantum interference effects that were first observed experimentally in 2003. It is shown that twisted rapid passage sweeps can be used to implement a universal set of quantum gates GU that operate with high-fidelity. The gate set GU consists of the Hadamard and NOT gates, together with variants of the ph...
متن کاملQuantum algorithm design using dynamic learning
We present a dynamic learning paradigm for " programming " a general quantum computer. A learning algorithm is used to find the control parameters for a coupled qubit system, such that the system at an initial time evolves to a state in which a given measurement corresponds to the desired operation. This can be thought of as a quantum neural network. We first apply the method to a system of two...
متن کاملHigh fidelity universal set of quantum gates using non-adiabatic rapid passage
Numerical simulation results are presented which suggest that a class of non-adiabatic rapid passage sweeps first realized experimentally in 1991 should be capable of implementing a universal set of quantum gates Gu that operate with high fidelity. The gates constituting Gu are the Hadamard and NOT gates, together with variants of the phase, π/8, and controlled-phase gates. The universality of ...
