Towards Lattice Surgery Compilation for the Color Code Using Pipe Diagrams
Laura S. Herzog, Gilad Kishony, Robert Wille +1
Pipe diagrams have emerged as a powerful framework for flexible lattice surgery compilation and spacetime optimization for the surface code. In contrast, analogous compilation tech…
Low-cost quantum error mitigation via auxiliary qubit return validation
Gilad Kishony, Avi Elazari, Ron Cohen +1
We introduce a low-overhead technique for quantum error mitigation based on post-selection using auxiliary qubit measurements. The method exploits the structural property that, in…
Optimal Approximation of Single Qubit Rotations within a Quantum Circuit
Gilad Kishony, Avi Elazari, Ron Cohen +1
Fault-tolerant quantum computing typically requires the transpilation of arbitrary quantum circuits into a finite, universal gate set, such as Clifford+T. As a baseline, Diagonal a…
Color code off-the-hook: avoiding hook errors with a single auxiliary per plaquette
Gilad Kishony, Austin Fowler
Syndrome extraction in the planar color code is complicated by high weight stabilizers and hook errors that can reduce the circuit-level distance. With a single auxiliary qubit per…
Surface code off-the-hook: diagonal syndrome-extraction scheduling
Gilad Kishony, Austin Fowler
In the rotated surface code, hook errors (errors on auxiliary qubits midway through syndrome extraction that propagate to correlated two-qubit data errors) can reduce the circuit-l…
Vari-Cool: a non-unitary quantum variational protocol for simulated cooling
Jeffrey Z. Song, Gilad Kishony, Erez Berg +1
We introduce a variational approach for preparing low energy states of arbitrary target Hamiltonians. The protocol is defined in terms of a repeated cycle consisting of p layers of…
Increasing the distance of topological codes with time vortex defects
Gilad Kishony, Erez Berg
We propose modifying topological quantum error correcting codes by incorporating space-time defects, termed ``time vortices,'' to reduce the number of physical qubits required to a…
Design and synthesis of scalable quantum programs
Tomer Goldfriend, Israel Reichental, Amir Naveh +42
We present a scalable, robust approach to creating quantum programs of arbitrary size and complexity. The approach is based on the true abstraction of the problem. The quantum prog…
Topological excitations at time vortices in periodically driven systems
Gilad Kishony, Ori Grossman, Netanel Lindner +2
We consider two-dimensional periodically driven systems of fermions with particle-hole symmetry. Such systems support non-trivial topological phases, including ones that cannot be…
Efficiently preparing chiral states via fermionic cooling on bosonic quantum hardware
Gilad Kishony, Mark S. Rudner, Erez Berg
Simulating many-body systems is one of the most promising applications of near-term quantum computers. An important open question is how to efficiently prepare the ground states of…
Gauged cooling of topological excitations and emergent fermions on quantum simulators
Gilad Kishony, Mark S. Rudner, Achim Rosch +1
Simulated cooling is a robust method for preparing low-energy states of many-body Hamiltonians on near-term quantum simulators. In such schemes, a subset of the simulator's spins (…
Converting electrons into emergent fermions at a superconductor-Kitaev spin liquid interface
Gilad Kishony, Erez Berg
We study an interface between a Kitaev spin liquid (KSL) in the chiral phase and a non-chiral superconductor. When the coupling across the interface is sufficiently strong, the int…
