Building a quantum computer that surpasses the computational power of its classical
counterpart is a great engineering challenge. Quantum software optimizations can provide …

Quantum computation is traditionally expressed in terms of quantum bits, or qubits. In this
work, we instead consider three-level qu trits. Past work with qutrits has demonstrated only …

For building a scalable quantum processor with superconducting qubits, ZZ interaction is of
great concern because its residual has a crucial impact to two-qubit gate fidelity. Two-qubit …

Near-term quantum computers are limited by the decoherence of qubits to only being able to
run low-depth quantum circuits with acceptable fidelity. This severely restricts what quantum …

Topological color codes are widely acknowledged as promising candidates for fault-tolerant
quantum computing. Neither a two-dimensional nor a three-dimensional topology, however …

High-fidelity two-qubit gates are crucial for the scalability of superconducting quantum
processors. While quantum information processing is typically based on qubits, qutrits (or …

Building a quantum computer is a daunting challenge since it requires good control but also
good isolation from the environment to minimize decoherence. It is therefore important to …

Dynamically correcting for unwanted interactions between a quantum system and its
environment is vital to achieving the high-fidelity quantum control necessary for a broad …

We conduct a systematic study of quantum circuits composed of multiple-control Z-rotation
(mczr) gates as primitives, since they are widely used components in quantum algorithms …
