QPerfect presented at the Q2B Paris

QPerfect’s ‘high-fidelity’ digital twins will help more accurately emulate how quantum computers work. Modeling quantum computers as faithfully as possible, including control equipment, to evaluate, compare, prototype and ultimately improve them: this is the ambition of QPerfect which, in a nascent quantum industry, wants to be the equivalent “EDA”, an acronym designating companies specializing in …

Publication: Optimizing Rydberg gates for logical qubit performance

Robust gate sequences are widely used to reduce the sensitivity of gate operations to experimental imperfections. Typically, the optimization minimizes the average gate error, however, recent work in quantum error correction has demonstrated that the performance of encoded logical qubits is sensitive to not only the average error rate, but also the type of errors …

Preprint: Non-Local Multi-Qubit Quantum Gates via a Driven Cavity

We present two protocols for implementing deterministic non-local multi-qubit quantum gates on qubits coupled to a common cavity mode. The protocols rely only on a classical drive of the cavity modes, while no external drive of the qubits is required. In the first protocol, the state of the cavity follows a closed trajectory in phase …

Publication: Robust phase-controlled gates for scalable atomic quantum processors

QPerfect researchers have put forward a simple scheme for realizing robust optically controlled quantum gates for scalable atomic quantum processors by driving the qubits with optical standing waves. Compared to existing strategies based on travelling wave lasers, atoms localized close to the antinodes of an optical standing wave can be made to realize phase-controlled quantum …
