A universal fault-tolerant quantum computer that can efficiently solve problems such as
integer factorization and unstructured database search requires millions of qubits with low …

The concept of quantum computing has inspired a whole new generation of scientists,
including physicists, engineers, and computer scientists, to fundamentally change the …

We present t| ket⟩, a quantum software development platform produced by Cambridge
Quantum Computing Ltd. The heart of t| ket⟩ is a language-agnostic optimising compiler …

Crosstalk is a major source of noise in Noisy Intermediate-Scale Quantum (NISQ) systems
and is a fundamental challenge for hardware design. When multiple instructions are …

The recent progress in the physical realization of quantum computers (the first publicly
available ones---IBM's QX architectures---have been launched in 2017) has motivated …

Quantum volume (QV) has become the de-facto standard benchmark to quantify the
capability of noisy intermediate-scale quantum (NISQ) devices. While QV values are often …

Quantum software tools for a wide variety of design tasks on and across different levels of
abstraction are crucial in order to eventually realize useful quantum applications. This …

In May of 2016, IBM Research has made a quantum processor available in the cloud to the
general public. The possibility of programming an actual quantum device has elicited much …

Quantum computers promise substantial speedups over conventional machines for many
practical applications. While considered" dreams of the future" for a long time, first quantum …

We present QUEST, a procedure to systematically generate approximations for quantum
circuits to reduce their CNOT gate count. Our approach employs circuit partitioning for …
