Qubit energy tuner based on single flux quantum circuits

Frontiers in Physics, 2023
A device called the qubit energy tuner (QET), based on single flux quantum (SFQ) circuits, has been proposed for Z control of superconducting qubits. The QET is created by improving flux digital-to-analog converters (flux DACs).

Classical simulations of noisy variational quantum circuits. [PDF]

npj Quantum Inf
Noise detrimentally affects quantum computations so that they not only become less accurate but also easier to simulate classically as systems scale up.

Reducing CNOT count in quantum Fourier transform for the linear nearest-neighbor architecture

Scientific Reports, 2023
Physical limitations of quantum hardware often necessitate nearest-neighbor (NN) architecture. When synthesizing quantum circuits using the basic gate library, which consists of CNOT and single-qubit gates, CNOT gates are required to convert a quantum ...

On the realistic worst case analysis of quantum arithmetic circuits

, 2022
Publisher Copyright: AuthorWe provide evidence that commonly held intuitions when designing quantum circuits can be misleading. In particular, we show that 1) reducing the T-count can increase the total depth; 2) it may be beneficial to trade controlled ...

Using the qubus for quantum computing [PDF]

, 2011
In this thesis I explore using the qubus for quantum computing. The qubus is an architecture of quantum computing, where a continuous variable ancilla is used to generate operations between matter qubits. I concentrate on using the qubus for two purposes
