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…

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…

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…

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…

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…

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…
