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…

Broadening of the drumhead mode spectrum due to in-plane thermal fluctuations of two-dimensional trapped ion crystals in a Penning trap

Athreya Shankar, Chen Tang, Matthew Affolter +5

Two-dimensional crystals of ions stored in Penning traps are a leading platform for quantum simulation and sensing experiments. For small amplitudes, the out-of-plane motion of suc…

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…

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…

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…

Breaking even with magic: demonstration of a high-fidelity logical non-Clifford gate

Shival Dasu, Simon Burton, Karl Mayer +7

Encoding quantum information to protect it from errors is essential for performing large-scale quantum computations. Performing a universal set of quantum gates on encoded states d…
