A Race Track Trapped-Ion Quantum Processor
S. A. Moses, C. H. Baldwin, M. S. Allman +93
We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race t…
Experimental demonstration of the advantage of adaptive quantum circuits
Michael Foss-Feig, Arkin Tikku, Tsung-Cheng Lu +16
Adaptive quantum circuits employ unitary gates assisted by mid-circuit measurement, classical computation on the measurement outcome, and the conditional application of future unit…
Implementing Fault-tolerant Entangling Gates on the Five-qubit Code and the Color Code
C. Ryan-Anderson, N. C. Brown, M. S. Allman +34
We compare two different implementations of fault-tolerant entangling gates on logical qubits. In one instance, a twelve-qubit trapped-ion quantum computer is used to implement a n…
Re-examining the quantum volume test: Ideal distributions, compiler optimizations, confidence intervals, and scalable resource estimations
Charles H. Baldwin, Karl Mayer, Natalie C. Brown +2
The quantum volume test is a full-system benchmark for quantum computers that is sensitive to qubit number, fidelity, connectivity, and other quantities believed to be important in…
Application-Oriented Performance Benchmarks for Quantum Computing
Thomas Lubinski, Sonika Johri, Paul Varosy +6
In this work we introduce an open source suite of quantum application-oriented performance benchmarks that is designed to measure the effectiveness of quantum computing hardware at…
A short note on the 0-fidelity
Karl Mayer
A recent article introduced a hierarchy of quantities called -fidelities that approximate the quantum process fidelity with increasing accuracy. The lowest approximation in this…
Theory of mirror benchmarking and demonstration on a quantum computer
Karl Mayer, Alex Hall, Thomas Gatterman +8
A new class of protocols called mirror benchmarking was recently proposed to measure the system-level performance of quantum computers. These protocols involve circuits with random…
Certified Quantum Measurement of Majorana Fermions
Abu Ashik Md. Irfan, Karl Mayer, Gerardo Ortiz +1
We present a quantum self-testing protocol to certify measurements of fermion parity involving Majorana fermion modes. We show that observing a set of ideal measurement statistics…
Quantum gate teleportation between separated qubits in a trapped-ion processor
Yong Wan, Daniel Kienzler, Stephen D. Erickson +9
Large-scale quantum computers will require quantum gate operations between widely separated qubits. A method for implementing such operations, known as quantum gate teleportation (…
Quantum Process Fidelity Bounds from Sets of Input States
Karl Mayer, Emanuel Knill
We investigate the problem of bounding the quantum process fidelity given bounds on the fidelities between target states and the action of a process on a set of pure input states.…
Faithful conversion of propagating quantum information to mechanical motion
A. P. Reed, K. H. Mayer, J. D. Teufel +8
We convert propagating qubits encoded as superpositions of zero and one photons to the motion of a micrometer-sized mechanical resonator. Using quantum state tomography, we determi…
