Entanglement across separate silicon dies in a modular superconducting qubit device
We demonstrate a modular solid state architecture with deterministic inter-module coupling between four physically separate, interchangeable superconducting qubit integrated circuits.
Matchgate benchmarking: Scalable benchmarking of a continuous family of many-qubit gates
We propose a method to reliably and efficiently extract the fidelity of many-qubit quantum circuits composed of continuously parametrized two-qubit gates called matchgates.
Quantum logic gate synthesis as a Markov Decision Process
We investigate the feasibility of the assumption that a variety of tasks in quantum programming could be modeled as Markov Decision Processes by exploring its consequences for two of the simplest tasks in quantum programming: state preparation and gate compilation.
We introduce an approximate description of an N--qubit state, which contains sufficient information to estimate the expectation value of any observable with precision.
Assessing the influence of broadband instrumentation noise on parametrically modulated superconducting qubits
Low-pass filtering the AC signal used to drive two-qubit gates between the first and second harmonic frequencies can reduce qubit sensitivity to flux noise at the AC sweet spot.
