- Abstract: We present a technique for rapid site-selective control of the quantum state
of particles in a large array using a combination of a fast deflector (e.g. an
acousto-optic deflector) and a relatively slow spatial light modulator. The use
of spatial light modulators for site-selective quantum state manipulation has
been limited due to slow transition times preventing rapid, consecutive quantum
gates. By partitioning the spatial light modulator into multiple segments, and
using a fast deflector to transition between them, it is possible to
substantially reduce the average time increment between scanner transitions by
increasing the number of gates that can be performed for a single spatial light
modulator full frame setting. We analyze the performance of this device in two
different configurations: in configuration 1, each segment of the spatial light
modulator addresses the full qubit array; in configuration 2, each segment of
the spatial light modulator addresses a sub-array and an additional fast
deflector positions that sub-array with respect to the full qubit array. With
these hybrid scanners we calculate qubit addressing rates that are tens to
hundreds of times faster than using an SLM alone.

We propose and demonstrate an efficient method for entangling emitters with optical transitions separated by many linewidths.
In our approach, electro-optic modulators enable a single photon to herald a parity measurement on a pair of spin qubits.
Working with distinguishable emitters allows for individual qubit addressing and readout, enabling parallel control and entanglement of both co-located and spatially separated emitters.

spatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information.
Current approaches for dynamically generating and measuring these modes are slow, due to the need to reconfigure a high-resolution phase mask.
We experimentally realize this approach, using a double-pass AOM to generate one of five orbital angular momentum states.
We are able to reconstruct arbitrary states in under 1 ms with an average fidelity of 96.9%.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
