Efficiently computing the Uhlmann fidelity for density matrices
Andrew J. Baldwin, Jonathan A. Jones
We consider the problem of efficiently computing the Uhlmann fidelity in the case when explicit density matrix descriptions are available. We derive an alternative formula which is…
Transforming pure and mixed states using an NMR quantum homogeniser
Maria Violaris, Gaurav Bhole, Jonathan A. Jones +2
The universal quantum homogeniser can transform a qubit from any state to any other state with arbitrary accuracy, using only unitary transformations to perform this task. Here we…
Drive-noise tolerant optical switching inspired by composite pulses
J. F. F. Bulmer, J. A. Jones, I. A. Walmsley
Electro-optic modulators within Mach--Zehnder interferometers are a common construction for optical switches in integrated photonics. A challenge faced when operating at high switc…
Efficient Hamiltonian programming in qubit arrays with nearest-neighbour couplings
Takahiro Tsunoda, Gaurav Bhole, Stephen A. Jones +2
We consider the problem of selectively controlling couplings in a practical quantum processor with always-on interactions that are diagonal in the computational basis, using sequen…
A robust entangling gate for polar molecules using magnetic and microwave fields
Michael Hughes, Matthew D. Frye, Rahul Sawant +7
Polar molecules are an emerging platform for quantum technologies based on their long-range electric dipole-dipole interactions, which open new possibilities for quantum informatio…
Rescaling interactions for quantum control
Gaurav Bhole, Takahiro Tsunoda, Peter J. Leek +1
A powerful control method in experimental quantum computing is the use of spin echoes, employed to select a desired term in the system's internal Hamiltonian, while refocusing othe…
