Density theorems with applications in quantum signal processing
Rahul Sarkar, Theodore J. Yoder
We study the approximation capabilities of two families of univariate polynomials that arise in applications of quantum signal processing. Although approximation only in the domain…
Calibrated decoders for experimental quantum error correction
Edward H. Chen, Theodore J. Yoder, Youngseok Kim +6
Arbitrarily long quantum computations require quantum memories that can be repeatedly measured without being corrupted. Here, we preserve the state of a quantum memory, notably wit…
Scalable error mitigation for noisy quantum circuits produces competitive expectation values
Youngseok Kim, Christopher J. Wood, Theodore J. Yoder +4
Noise in existing quantum processors only enables an approximation to ideal quantum computation. However, these approximations can be vastly improved by error mitigation, for the c…
A graph-based formalism for surface codes and twists
Rahul Sarkar, Theodore J. Yoder
Twist defects in surface codes can be used to encode more logical qubits, improve the code rate, and implement logical gates. In this work we provide a rigorous formalism for const…
