Hardware optimized parity check gates for superconducting surface codes
Matthew J. Reagor, Thomas C. Bohdanowicz, David Rodriguez Perez +2
Error correcting codes use multi-qubit measurements to realize fault-tolerant quantum logic steps. In fact, the resources needed to scale-up fault-tolerant quantum computing hardwa…
End-to-end resource analysis for quantum interior point methods and portfolio optimization
Alexander M. Dalzell, B. David Clader, Grant Salton +8
We study quantum interior point methods (QIPMs) for second-order cone programming (SOCP), guided by the example use case of portfolio optimization (PO). We provide a complete quant…
A Q# Implementation of a Quantum Lookup Table for Quantum Arithmetic Functions
Rajiv Krishnakumar, Mathias Soeken, Martin Roetteler +1
In this paper, we present Q# implementations for arbitrary single-variabled fixed-point arithmetic operations for a gate-based quantum computer based on lookup tables (LUTs). In ge…
Automated quantum error mitigation based on probabilistic error reduction
Benjamin McDonough, Andrea Mari, Nathan Shammah +4
Current quantum computers suffer from a level of noise that prohibits extracting useful results directly from longer computations. The figure of merit in many near-term quantum alg…
Testing platform-independent quantum error mitigation on noisy quantum computers
Vincent Russo, Andrea Mari, Nathan Shammah +2
We apply quantum error mitigation techniques to a variety of benchmark problems and quantum computers to evaluate the performance of quantum error mitigation in practice. To do so,…
Quantum Resources Required to Block-Encode a Matrix of Classical Data
B. David Clader, Alexander M. Dalzell, Nikitas Stamatopoulos +3
We provide modular circuit-level implementations and resource estimates for several methods of block-encoding a dense matrix of classical data to precision ; the min…
Error mitigation increases the effective quantum volume of quantum computers
Ryan LaRose, Andrea Mari, Vincent Russo +2
Quantum volume is a single-number metric which, loosely speaking, reports the number of usable qubits on a quantum computer. While improvements to the underlying hardware are a dir…
Analyzing the impact of time-correlated noise on zero-noise extrapolation
Kevin Schultz, Ryan LaRose, Andrea Mari +4
Zero-noise extrapolation is a quantum error mitigation technique that has typically been studied under the ideal approximation that the noise acting on a quantum device is not time…
