Implementing a strand of a scalable fault-tolerant quantum computing fabric
Jerry M. Chow, Jay M. Gambetta, Easwar Magesan +7
Quantum error correction (QEC) is an essential step towards realising scalable quantum computers. Theoretically, it is possible to achieve arbitrarily long protection of quantum in…
Tractable Simulation of Error Correction with Honest Approximations to Realistic Fault Models
Daniel Puzzuoli, Christopher Granade, Holger Haas +3
In previous work, we proposed a method for leveraging efficient classical simulation algorithms to aid in the analysis of large-scale fault tolerant circuits implemented on hypothe…
Investigating the limits of randomized benchmarking protocols
Jeffrey M. Epstein, Andrew W. Cross, Easwar Magesan +1
In this paper, we analyze the performance of randomized benchmarking protocols on gate sets under a variety of realistic error models that include systematic rotations, amplitude d…
Compressing measurements in quantum dynamic parameter estimation
Easwar Magesan, Alexandre Cooper, Paola Cappellaro
We present methods that can provide an exponential savings in the resources required to perform dynamic parameter estimation using quantum systems. The key idea is to merge classic…
Reconstructing the Profile of Time-Varying Magnetic Fields With Quantum Sensors
Easwar Magesan, Alexandre Cooper, Honam Yum +1
Quantum systems have shown great promise for precision metrology thanks to advances in their control. This has allowed not only the sensitive estimation of external parameters but…
Time-resolved magnetic sensing with electronic spins in diamond
Alexandre Cooper, Easwar Magesan, Honam Yum +1
Quantum probes can measure time-varying fields with high sensitivity and spatial resolution, enabling the study of biological, material, and physical phenomena at the nanometer sca…
