Error-corrected Hadamard gate simulated at the circuit level
György P. Gehér, Campbell McLauchlan, Earl T. Campbell +2
We simulate the logical Hadamard gate in the surface code under a circuit-level noise model, compiling it to a physical circuit on square-grid connectivity hardware. Our paper is t…
Isometric rigidity of Wasserstein spaces over Euclidean spheres
György Pál Gehér, Aranka Hrušková, Tamás Titkos +1
We study the structure of isometries of the quadratic Wasserstein space over the sphere endowed with the distance inherited from…
Tangling schedules eases hardware connectivity requirements for quantum error correction
Gyorgy P. Geher, Ophelia Crawford, Earl T. Campbell
Quantum computers have the potential to change the way we solve computational problems. Due to the noisy nature of qubits, the need arises to correct physical errors occurring duri…
Compilation of a simple chemistry application to quantum error correction primitives
Nick S. Blunt, György P. Gehér, Alexandra E. Moylett
A number of exciting recent results have been seen in the field of quantum error correction. These include initial demonstrations of error correction on current quantum hardware, a…
When is the variance of one observable less than or equal to that of another with respect to all quantum states?
György Pál Gehér, Nazar Miheisi
In quantum mechanics, the well-known Loewner order expresses that one observable's expectation value is less than or equal than that of another with respect to all quantum states.…
