Two-Qubit Gates for Resonant Exchange Qubits [PDF]

open access: yesPhysical Review Letters, 2013
A new approach to single-qubit operations using exchange interactions of single electrons in gate-defined quantum dots has recently been demonstrated: the resonant exchange qubit. We show that two-qubit operations, specifically the CPHASE gate, can be performed between resonant exchange qubits very straightforwardly, using a single exchange pulse. This

A Pair of Coupled Waveguides as a Classical Analogue for a Solid-State Qubit

open access: yesSensors, 2022
We have determined conditions when a pair of coupled waveguides, a common element for integrated room-temperature photonics, can act as a qubit based on a system with a double-well potential.

A single photon produces general W state of N qubits and its application [PDF]

open access: yes, 2007
Based on the Wu's scheme[1], We prepare the general N-qubit W state. We find that the concurrence of two qubits in general N-qubit W state is only related to their coefficients and we successfully apply the general N-qubit W state to quantum state ...

SoK: Benchmarking the Performance of a Quantum Computer

open access: yesEntropy, 2022
The quantum computer has been claimed to show more quantum advantage than the classical computer in solving some specific problems. Many companies and research institutes try to develop quantum computers with different physical implementations. Currently,

Gravitational Qubits [PDF]

open access: yesUniverse, 2019
We report on the behavior of two-level quantum systems, or qubits, in the background of rotating and non-rotating metrics and provide a method to derive the related spin currents and motions. The calculations are performed in the external field approximation.

Quantum Logic Locking for Security

open access: yesJ, 2023
Having access to a unique quantum circuit that one wants to protect against use by others is a very likely scenario in industrial computing. However, currently, users rely on classical computer security schemes, which have known shortcomings.

Topological quantum gate entangler for a multi-qubit state [PDF]

open access: yes, 2007
We establish a relation between topological and quantum entanglement for a multi-qubit state by considering the unitary representations of the Artin braid group. We construct topological operators that can entangle multi-qubit state.
