The parameter-shift rule is an approach to measuring gradients of quantum circuits with respect to their parameters, which does not require ancilla qubits or...
Notes on the circuit model of quantum computing. Currently mostly an exposition on the menagerie of quantum gates on 2-qubits.
For a native gate set which includes all single-qubit gates, we apply results from symplectic geometry to analyze the spaces of two-qubit programs accessible...
