Quantum Sensing with Erasure Qubits.
Pradeep Niroula, Jack Dolde, Xin Zheng +7 more·Oct 2, 2023
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 date, research on erasure qubits has primar...
Redheffer: Trig to Quantum Error Bounds
H. Yun·Oct 2, 2023
In the existing literature, the Redheffer inequality is typically proven using mathematical induction. In this short paper, we present a straightforward proof of this inequality by leveraging trigonometric substitution. We then extend the Redheffer i...
