Quantum error correction well below the color code threshold
Ali Lavasani, Adam P. Reed, Joan M. Dreiling +20
Quantum error correction enables scalable fault-tolerant quantum computation by suppressing logical errors exponentially with code distance once physical error rates fall below a c…
Logical gate set tomography
Piper C. Wysocki, Juan Gonzalez De Mendoza, Karl Mayer +11
Quantum error correction (QEC) can strongly suppress noise, but predicting whether a computation succeeds requires understanding not only how much effective noise persists after QE…
Genons, Double Covers and Fault-tolerant Clifford Gates
Simon Burton, Elijah Durso-Sabina, Natalie C. Brown
A great deal of work has been done developing quantum codes with varying overhead and connectivity constraints. However, given the such an abundance of codes, there is a surprising…
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…
Controlled Gate Networks: Theory and Application to Eigenvalue Estimation
Max Bee-Lindgren, Zhengrong Qian, Matthew DeCross +5
We introduce a new scheme for quantum circuit design called controlled gate networks. Rather than trying to reduce the complexity of individual unitary operations, the new strategy…
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…
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…
Resource-Efficient Quantum Computing by Breaking Abstractions
Yunong Shi, Pranav Gokhale, Prakash Murali +11
Building a quantum computer that surpasses the computational power of its classical counterpart is a great engineering challenge. Quantum software optimizations can provide an acce…
Critical faults of leakage errors on the surface code
Natalie C. Brown, Andrew W. Cross, Kenneth R. Brown
Leakage is a particularly damaging error that occurs when a qubit leaves the defined computational subspace. Leakage errors limit the effectiveness of quantum error correcting code…
Asymptotic Improvements to Quantum Circuits via Qutrits
Pranav Gokhale, Jonathan M. Baker, Casey Duckering +3
Quantum computation is traditionally expressed in terms of quantum bits, or qubits. In this work, we instead consider three-level qu. Past work with qutrits has demonstrated…
Leakage mitigation for quantum error correction using a mixed qubit scheme
Natalie C. Brown, Kenneth R. Brown
Leakage errors take qubits out of the computational subspace and will accumulate if not addressed. A leaked qubit will reduce the effectiveness of quantum error correction protocol…
Handling Leakage with Subsystem Codes
Natalie C. Brown, Michael Newman, Kenneth R. Brown
Leakage is a particularly damaging error that occurs when a qubit state falls out of its two-level computational subspace. Compared to independent depolarizing noise, leaked qubits…
Comparing Zeeman qubits to hyperfine qubits in the context of the surface code: Yb and Yb
Natalie C. Brown, Kenneth R. Brown
Many systems used for quantum computing possess additional states beyond those defining the qubit. Leakage out of the qubit subspace must be considered when designing quantum error…
