The Toffoli gate is a three-quantum-bit (three-qubit) operation that inverts the state of a target
qubit conditioned on the state of two control qubits. It makes universal reversible classical …

We present a method to implement ultrafast two-qubit gates valid for the ultrastrong coupling
and deep strong coupling regimes of light-matter interaction, considering state-of-the-art …

A practical quantum computer must be capable of performing high fidelity quantum gates on
a set of quantum bits (qubits). In the presence of noise, the realization of such gates poses …

A possible building block for a scalable quantum computer has recently been demonstrated
[Mariantoni et al., Science 334, 61 (2011) SCIEAS 0036-8075 10.1126/science. 1208517] …

The recent realization of a coherent interface between a single electron in a silicon quantum
dot and a single photon trapped in a superconducting cavity opens the way for implementing …

Quantum computing architectures are on the verge of scalability, a key requirement for the
implementation of a universal quantum computer. The next stage in this quest is the …

Sideband transitions have been shown to generate controllable interaction between
superconducting qubits and microwave resonators. Up to now, these transitions have been …

We present an indirect two-qubit parity meter in planar circuit quantum electrodynamics,
realized by discrete interaction with an ancilla and a subsequent projective ancilla …

Efficient communication between qubits relies on robust networks, which allow for fast and
coherent transfer of quantum information. It seems natural to harvest the remarkable …

We investigate a hybrid quantum system consisting of spatially separated resonant
exchange qubits, defined in three-electron semiconductor triple quantum dots, that are …
