Two-Qubit Gates for Resonant Exchange Qubits [PDF]
Physical 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

SoK: Benchmarking the Performance of a Quantum Computer
Entropy, 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,

A hole spin qubit in a fin field-effect transistor above 4 kelvin [PDF]
Nature Electronics, 2021 The greatest challenge in quantum computing is achieving scalability. Classical computing, which previously faced such issues, currently relies on silicon chips hosting billions of fin field-effect transistors.

Universe, 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.

Resonator–zero-qubit architecture for superconducting qubits [PDF]
Physical Review A, 2012 We analyze the performance of the Resonator/zero-Qubit (RezQu) architecture in which the qubits are complemented with memory resonators and coupled via a resonator bus. Separating the stored information from the rest of the processing circuit by at least two coupling steps and the zero qubit state results in a significant increase of the ON/OFF ratio ...

Quantum Logic Locking for Security
J, 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.

Entanglement-based single-shot detection of a single magnon with a superconducting qubit [PDF]
Science, 2019 Detecting a single magnetic excitation Quantum-enhanced sensing is one of the near-term applications for the developing field of quantum technologies. A promising approach to quantum sensing relies on entangling a well-controlled system (the sensor) to ...
