Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

Over the last two decades, tremendous advances have been made for constructing large-
scale quantum computers. In particular, quantum computing platforms based on …

Scalable generation of genuine multipartite entanglement with an increasing number of
qubits is important for both fundamental interest and practical use in quantum-information …

Long-range entanglement—the backbone of topologically ordered states—cannot be
created in finite time using local unitary circuits, or, equivalently, adiabatic state preparation …

To run large-scale algorithms on a quantum computer, error-correcting codes must be able
to perform a fundamental set of operations, called logic gates, while isolating the encoded …

Due to its properties, lithium niobate is one of the most suitable material platforms for the
implementation of integrated optical quantum circuits. With the commercialization of lithium …

To date, quantum computation on real, physical devices has largely been limited to simple,
time-ordered sequences of unitary operations followed by a final projective measurement …

The duration and fidelity of qubit readout are critical factors for applications in quantum-
information processing as they limit the fidelity of algorithms which reuse qubits after …

Active qubit reset is a key operation in many quantum algorithms, and particularly in
quantum error correction. Here, we experimentally demonstrate a reset scheme for a three …

Quantum computing is considered as a next-generation information processing technology.
The basic element of a quantum computing system is a quantum bit, often called a qubit …
