Qutrit Toric Code and Parafermions in Trapped Ions
Mohsin Iqbal, Anasuya Lyons, Chiu Fan Bowen Lo +16
The development of programmable quantum devices can be measured by the complexity of manybody states that they are able to prepare. Among the most significant are topologically ord…
Experimental Demonstration of Break-Even for the Compact Fermionic Encoding
Ramil Nigmatullin, Kevin Hemery, Khaldoon Ghanem +8
The utility of solving the Fermi-Hubbard model has been estimated in the billions of dollars. Digital quantum computers can in principle address this task, but have so far been lim…
Experiments with the 4D Surface Code on a QCCD Quantum Computer
Noah Berthusen, Joan Dreiling, Cameron Foltz +9
Single-shot quantum error correction has the potential to speed up quantum computations by removing the need for multiple rounds of syndrome extraction in order to be fault-toleran…
The computational power of random quantum circuits in arbitrary geometries
Matthew DeCross, Reza Haghshenas, Minzhao Liu +49
Empirical evidence for a gap between the computational powers of classical and quantum computers has been provided by experiments that sample the output distributions of two-dimens…
High-fidelity and Fault-tolerant Teleportation of a Logical Qubit using Transversal Gates and Lattice Surgery on a Trapped-ion Quantum Computer
C. Ryan-Anderson, N. C. Brown, C. H. Baldwin +21
Quantum state teleportation is commonly used in designs for large-scale fault-tolerant quantum computers. Using Quantinuum's H2 trapped-ion quantum processor, we implement the firs…
Benchmarking logical three-qubit quantum Fourier transform encoded in the Steane code on a trapped-ion quantum computer
Karl Mayer, Ciarán Ryan-Anderson, Natalie Brown +20
We implement logically encoded three-qubit circuits for the quantum Fourier transform (QFT), using the [[7,1,3]] Steane code, and benchmark the circuits on the Quantinuum H2-1 trap…
Demonstration of logical qubits and repeated error correction with better-than-physical error rates
A. Paetznick, M. P. da Silva, C. Ryan-Anderson +29
The promise of quantum computers hinges on the ability to scale to large system sizes, e.g., to run quantum computations consisting of more than 100 million operations fault-tolera…
Fault-Tolerant One-Bit Addition with the Smallest Interesting Colour Code
Yang Wang, Selwyn Simsek, Thomas M. Gatterman +9
Fault-tolerant operations based on stabilizer codes are the state of the art in suppressing error rates in quantum computations. Most such codes do not permit a straightforward imp…
Evidence of Scaling Advantage for the Quantum Approximate Optimization Algorithm on a Classically Intractable Problem
Ruslan Shaydulin, Changhao Li, Shouvanik Chakrabarti +26
The quantum approximate optimization algorithm (QAOA) is a leading candidate algorithm for solving optimization problems on quantum computers. However, the potential of QAOA to tac…
Probing critical states of matter on a digital quantum computer
Reza Haghshenas, Eli Chertkov, Matthew DeCross +11
Although quantum mechanics underpins the microscopic behavior of all materials, its effects are often obscured at the macroscopic level by thermal fluctuations. A notable exception…
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

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…
