Adaptive Procedures for Discrimination Between Arbitrary Tensor-Product Quantum States
Sarah Brandsen, Mengke Lian, Kevin D. Stubbs +2
Discrimination between quantum states is a fundamental task in quantum information theory. Given two arbitrary tensor-product quantum states (TPQS) $ρ_{\pm} = ρ_{\pm}^{(1)} \otimes…
On Optimality of CSS Codes for Transversal
Narayanan Rengaswamy, Robert Calderbank, Michael Newman +1
In order to perform universal fault-tolerant quantum computation, one needs to implement a logical non-Clifford gate. Consequently, it is important to understand codes that impleme…
Logical Clifford Synthesis for Stabilizer Codes
Narayanan Rengaswamy, Robert Calderbank, Swanand Kadhe +1
Quantum error-correcting codes are used to protect qubits involved in quantum computation. This process requires logical operators, acting on protected qubits, to be translated int…
Kerdock Codes Determine Unitary 2-Designs
Trung Can, Narayanan Rengaswamy, Robert Calderbank +1
The non-linear binary Kerdock codes are known to be Gray images of certain extended cyclic codes of length over . We show that exponentiating these $\mathbb…
Unifying the Clifford Hierarchy via Symmetric Matrices over Rings
Narayanan Rengaswamy, Robert Calderbank, Henry D. Pfister
The Clifford hierarchy is a foundational concept for universal quantum computation (UQC). It was introduced to show that UQC can be realized via quantum teleportation, given access…
