Quantum error correction of a grid-state qubit with state preparation and measurement errors below
Sara Turcotte, Lucas St-Jean, Amélie L. Pessonneaux +10
Grid state qubits offer a hardware-efficient approach to large-scale fault-tolerant quantum computing. They access the information redundancy required for quantum error correction…
Optimization of High-Fidelity Single-Qubit Gates for Fluxoniums Using Single-Flux Quantum Control
Maxime Lapointe-Major, Boyan Torosov, Bohdan Kulchytskyy +1
We present a gradient-based method to construct memory-efficient, high-fidelity, single-qubit gates for fluxonium qubits. These gates are constructed using a sequence of single-flu…
Optimization of Two-Qubit Gates in Tunable-Coupler Architectures Using Single Flux Quantum Control
Boyan Torosov, Bohdan Kulchytskyy, Florian Hopfmueller +3
We present a gradient-based method to construct high-fidelity, two-qubit quantum gates in a system consisting of two transmon qubits coupled via a tunable coupler. In particular, w…
How to Build a Quantum Supercomputer: Scaling from Hundreds to Millions of Qubits
Masoud Mohseni, Artur Scherer, K. Grace Johnson +48
In the span of four decades, quantum computation has evolved from an intellectual curiosity to a potentially realizable technology. Today, small-scale demonstrations have become po…
Optimizing Multi-level Magic State Factories for Fault-Tolerant Quantum Architectures
Allyson Silva, Artur Scherer, Zak Webb +11
We propose a novel technique for optimizing a modular fault-tolerant quantum computing architecture, taking into account any desired space-time trade-offs between the number of phy…
Bootstrapping Classical Shadows for Neural Quantum State Tomography
Wirawat Kokaew, Bohdan Kulchytskyy, Shunji Matsuura +1
We investigate the advantages of using autoregressive neural quantum states as ansatze for classical shadow tomography to improve its predictive power. We introduce a novel estimat…
