Objective
Quantum many-body states can be classified by whether they can be generated in finite time using only local interactions. States for which this is impossible possess long-range entanglement and underpin key advances in quantum information science. They appear as ground states in condensed matter, as optimal metrological resources, and as building blocks for fault-tolerant computation, yet they are hard to prepare on noisy, shallow-depth hardware because long evolutions accumulate errors. Measurement-based quantum computing (MBQC) offers a route: by performing adaptive local measurements on certain resource states, long-range entanglement can be created in bounded depth. However, applying tools from MBQC in matter qubits has been hampered by low-fidelity, small-scale mid-circuit measurements.
In this proposal, I aim to overcome this barrier by designing and building an adaptive neutral-atom processor. The platform combines scalability, long coherence, and high-fidelity readout; our recent experiments have demonstrated high-fidelity two-qubit gates and mid-circuit readout. The proposed processor will generate large graph states of trapped atoms, perform high-fidelity mid-circuit measurements, and implement low-latency feedforward.
With this capability we will engineer and probe measurement-induced phases of matter, from single-round to multi-round protocols and higher-dimensional connectivity. We will exploit these states to (i) enhance atomic-clock precision beyond standard limits, (ii) explore non-equilibrium many-body dynamics and phase transitions, and (iii) realize topologically protected operations for fault-tolerant quantum computing.
By uniting MBQC with neutral-atom hardware, this project establishes a scalable route to prepare and exploit long-range-entangled states on near-term processors and, ultimately, in fault-tolerant architectures.
