Field programmable spin arrays for scalable quantum repeaters

 In the progress report, it was noted that for “quantum computational advantage” in harnessing many-body quantum stages with spins, large scale control over thousands of spin qubits and their interaction was needed, but was limited by power consumption and cross-talk inherent in current microwave techniques. To this end, we analyzed the problem from first principles...

Photonic Circuits to Program Atoms at Scale

How do we control large numbers of qubits? This is a question being asked across quantum information science, including for atomic qubits. Unlike other varieties of qubits—such as superconducting qubits, where control signals are primarily electrical—atomic qubits are controlled by beams of light. Individual control over each atomic qubit requires modulating many individual optical beams....

A Polariton-Stabilized Spin Clock

Figure: A polaritonic-stabilized spin clock. The reference probe field at frequency ω with intensity I is is split into a local oscillator and probe. The latter is sent to the resonant system, which consists of NV centers in diamond with population relaxation rate γ coupled to a microwave cavity at rate g. Atomic clocks are...

Scalable assembly of artificial atoms in photonic chips

A central goal in quantum information processing is the development of scalable quantum processors and quantum networks. Towards this end, solid-state “artificial atoms” such as colour centres in diamond are especially promising because they combine efficient optical interfaces, minutes of spin coherence, and potentially very-large-scale fabrication. Indeed, in the past 20 years of quantum engineering,...

Transform-limited photons from a tin-vacancy spin in diamond

One of the goals of the CUA is to develop quantum networks: systems of stationary quantum memories connected by photons. Solid-state quantum emitters that combine coherent optical transitions, long-lived spin states, and the potential for scalability are critical components of future quantum information systems. Many emitters are candidates, with some desirable properties, but all have...

Semiconductor Quantum Technologies for Communications and Computing

Location:MIT 4-270

The field of quantum optics offers new ways to compute, communicate, and measure with quantum states. Recent advances in materials, quantum control, and nanofabrication now open the prospect for scalable quantum technologies based on solid-state quantum systems. In particular, photonic integrated circuits (PICs) now allow routing photons with high precision and low loss, and atom-like systems in semiconductors enable spin-based quantum memories that can be coupled to these optical circuits. The first part of this talk will review our recent progress in adapting one of the leading PIC architectures—silicon photonics—for various quantum secure communications protocols. The second part of the talk will consider how PIC technology, integrated with quantum memories, can extend the reach of quantum communications and form the basis of modular quantum computers.
