Automated Flag-based Fault-Tolerant State Preparation using Integer Linear Programming
Ben Criger, Aaron Hankin, Justin J. Burau +1
Post-selected stabilizer state preparation is a necessary subroutine in fault-tolerant quantum computation, both for initialization of logical qubits, and for logical-ancilla-based…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
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…
Topological Order from Measurements and Feed-Forward on a Trapped Ion Quantum Computer
Mohsin Iqbal, Nathanan Tantivasadakarn, Thomas M. Gatterman +13
Quantum systems evolve in time in one of two ways: through the Schrödinger equation or wavefunction collapse. So far, deterministic control of quantum many-body systems in the lab…
Characterizing a non-equilibrium phase transition on a quantum computer
Eli Chertkov, Zihan Cheng, Andrew C. Potter +13
At transitions between phases of matter, physical systems can exhibit universal behavior independent of their microscopic details. Probing such behavior in quantum many-body system…
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…
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…
Realizing a dynamical topological phase in a trapped-ion quantum simulator
Philipp T. Dumitrescu, Justin Bohnet, John Gaebler +6
Nascent platforms for programmable quantum simulation offer unprecedented access to new regimes of far-from-equilibrium quantum many-body dynamics in (approximately) isolated syste…
Realization of real-time fault-tolerant quantum error correction
C. Ryan-Anderson, J. G. Bohnet, K. Lee +14
Correcting errors in real time is essential for reliable large-scale quantum computations. Realizing this high-level function requires a system capable of several low-level primiti…
Holographic dynamics simulations with a trapped ion quantum computer
Eli Chertkov, Justin Bohnet, David Francois +10
Quantum computers have the potential to efficiently simulate the dynamics of many interacting quantum particles, a classically intractable task of central importance to fields rang…
Lifetime-Limited Interrogation of Two Independent Clocks Using Correlation Spectroscopy
E. R. Clements, M. E. Kim, K. Cui +7
Laser decoherence limits the stability of optical clocks by broadening the observable resonance linewidths and adding noise during the dead time between clock probes. Correlation s…

S. M. Brewer, J. -S. Chen, K. Beloy +14
We have measured the quadratic Zeeman coefficient for the optical clock transition in Al, ~MHz/T, an…
Systematic uncertainty due to background-gas collisions in trapped-ion optical clocks
A. M. Hankin, E. R. Clements, Y. Huang +5
We describe a framework for calculating the frequency shift and uncertainty of trapped-ion optical atomic clocks caused by background-gas collisions, and apply this framework to an…
