GHZ is All You Need: Quantum Sensing with VISTA
Oskar Novak, Christos N. Gagatsos, Narayanan Rengaswamy
Quantum metrology holds the potential to enhance magnetic field sensing beyond current limits. However, in the presence of realistic noise, this advantage degrades to the Standard…
Stabilizers for Compiling Logical Circuits under Hardware Constraints
Jack Weinberg, Narayanan Rengaswamy
To implement quantum algorithms on a quantum computer, we must overcome the twin problems of fault-tolerance -- how can we realize a relatively noiseless computation by cleverly co…
Networked Realization of Quantum LDPC Codes
Swayangprabha Shaw, Narayanan Rengaswamy
Quantum low-density parity-check (QLDPC) codes with good parameters are promising candidates for low-overhead fault-tolerant quantum computing, but their non-local stabilizers requ…
Quantum Repeater Protocol using Quantum Error Correction for Distillation
Ashlesha Patil, Michele Pacenti, Bane VasiÄ +2
Bell-state measurement (BSM) on entangled states shared between quantum repeaters is the fundamental operation used to route entanglement in quantum networks. Performing BSMs on We…
Explaining Robust Quantum Metrology by Counting Codewords
Oskar Novak, Narayanan Rengaswamy
Quantum sensing holds great promise for high-precision magnetic field measurements. However, its performance is significantly limited by noise. The investigation of active quantum…
Fault Tolerant Quantum Simulation via Symplectic Transvections
Zhuangzhuang Chen, Jack Owen Weinberg, Narayanan Rengaswamy
Conventional approaches to fault-tolerant quantum computing realize logical circuits gate-by-gate, synthesizing each gate independently on one or more code blocks. This incurs exce…
