Bell sampling from quantum circuits
2023 · arXiv (Cornell University)
A central challenge in the verification of quantum computers is benchmarking their performance as a whole and demonstrating their computational capabilities. In this work, we find a universal model of quantum computation, Bell sampling, that …

Quantum Sensing with Erasure Qubits
2023 · arXiv (Cornell University)
The dominant noise in an "erasure qubit" is an erasure -- a type of error whose occurrence and location can be detected. Erasure qubits have potential to reduce the overhead associated with fault tolerance. To …

Quantum Lego Expansion Pack: Enumerators from Tensor Networks
2024 · PRX Quantum
We provide the first tensor-network method for computing quantum weight enumerator polynomials in the most general form. If a quantum code has a known tensor-network construction of its encoding map, our method is far more …

On the complexity of sampling from shallow Brownian circuits
2024 · arXiv (Cornell University)
While many statistical properties of deep random quantum circuits can be deduced, often rigorously and other times heuristically, by an approximation to global Haar-random unitaries, the statistics of constant-depth random quantum circuits are generally less …
