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 …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Despite the high measurement fidelity that can now be reached, the dispersive qubit readout
of circuit quantum electrodynamics is plagued by a loss of its quantum nondemolition …

We review the physical phenomena that arise when quantum mechanical energy levels are
modulated in time. The dynamics resulting from changes in the transition frequency is a …

We demonstrate rapid, first-order sideband transitions between a superconducting resonator
and a frequency-modulated transmon qubit. The qubit contains a substantial asymmetry …

Autonomous quantum error correction (AQEC) protects logical qubits by engineered
dissipation and thus circumvents the necessity of frequent, error-prone measurement …

We demonstrate the time-resolved driving of two-photon blue sideband transitions between
superconducting qubits and a transmission line resonator. As an example of using these …

We present here a new approach to scalable quantum computing—a'qubus computer'—
which realizes qubit measurement and quantum gates through interacting qubits with a …

A current bottleneck for quantum computation is the realization of high-fidelity two-qubit
quantum operations between two or more quantum bits in arrays of coupled qubits. Gates …

A possible building block for a scalable quantum computer has recently been demonstrated
