Phase-Altered Interleaved Randomized Benchmarking for Compiled Non-Clifford Gates
Simona K. Grigorova, Nikolay V. Vitanov, Boyan T. Torosov
Interleaved randomized benchmarking (IRB) provides a scalable estimate of a gate's error rate, but its standard guarantees require the interleaved gate to be Clifford~\cite{Magesan…
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…
Motional state analysis of a trapped ion by ultra-narrowband composite pulses
Marion Mallweger, Milena Guevara-Bertsch, Boyan T. Torosov +7
In this work, we present a method for measuring the motional state of a two-level system coupled to a harmonic oscillator. Our technique uses ultra-narrowband composite pulses on t…
Narrowband composite two-qubit phase gates
Boyan T. Torosov, Nikolay V. Vitanov
We propose a method to construct composite two-qubit gates with narrowband profiles with respect to the spin-spin coupling. The composite sequences are selective to the variations…
