Microarchitectures for Heterogeneous Superconducting Quantum Computers
Samuel Stein, Sara Sussman, Teague Tomesh +12
Noisy Intermediate-Scale Quantum Computing (NISQ) has dominated headlines in recent years, with the longer-term vision of Fault-Tolerant Quantum Computation (FTQC) offering signifi…
Experimental quantum channel discrimination using metastable states of a trapped ion
Kyle DeBry, Jasmine Sinanan-Singh, Colin D. Bruzewicz +6
We present experimental demonstrations of accurate and unambiguous single-shot discrimination between three quantum channels using a single trapped ion. The th…
Semantic embedding for quantum algorithms
Zane M. Rossi, Isaac L. Chuang
The study of classical algorithms is supported by an immense understructure, founded in logic, type, and category theory, that allows an algorithmist to reason about the sequential…
Quantum signal processing with continuous variables
Zane M. Rossi, Victor M. Bastidas, William J. Munro +1
Quantum singular value transformation (QSVT) enables the application of polynomial functions to the singular values of near arbitrary linear operators embedded in unitary transform…
Power of sequential protocols in hidden quantum channel discrimination
Sho Sugiura, Arkopal Dutt, William J. Munro +2
In many natural and engineered systems, unknown quantum channels act on a subsystem that cannot be directly controlled and measured, but is instead learned through a controllable s…
Error Correction of Quantum Algorithms: Arbitrarily Accurate Recovery Of Noisy Quantum Signal Processing
Andrew K. Tan, Yuan Liu, Minh C. Tran +1
The intrinsic probabilistic nature of quantum systems makes error correction or mitigation indispensable for quantum computation. While current error-correcting strategies focus on…
