Quantum optimal control of the Dicke manifold in dipolar Rydberg atom arrays

Ivy Pannier-Günther, Vikas Buchemmavari, Pablo M. Poggi +1

The ability to engineer and control quantum states of many-body systems is a central challenge in quantum information science. For a register of qubits, the full Hilbert space…

Holstein Primakoff spin codes for local and collective noise

Sivaprasad Omanakuttan, Tyler Thurtell, Andrew K. Forbes +2

Quantum error correction is essential for fault-tolerant quantum computation, yet most existing codes rely on local control and stabilizer measurements that are difficult to implem…

An asymmetric and fast Rydberg gate protocol for entanglement outside of the blockade regime

Daniel C. Cole, Vikas Buchemmavari, Mark Saffman

We analyze a new Rydberg gate design based on the original protocol [Jaksch, et. al. Phys. Rev. Lett. {\bf 85}, 2208 (2000)] that is modified to enable high fidelity opera…

Coherence Preserving Leakage Detection and Cooling in Alkaline Earth Atoms

Sivaprasad Omanakuttan, Vikas Buchemmavari, Michael J. Martin +1

Optically trapped atoms in arrays of optical tweezers have emerged as a powerful platform for quantum information processing given the recent demonstrations of high-fidelity quantu…

Circuit-based leakage-to-erasure conversion in a neutral atom quantum processor

Matthew N. H. Chow, Vikas Buchemmavari, Sivaprasad Omanakuttan +4

Leakage out of the computational subspace is a major limitation of current state-of-the-art neutral-atom quantum computers and a significant challenge for scalable systems. In a qu…

Fault-tolerant quantum computation using large spin cat-codes

Sivaprasad Omanakuttan, Vikas Buchemmavari, Jonathan A. Gross +2

We construct a fault-tolerant quantum error-correcting protocol based on a qubit encoded in a large spin qudit using a spin-cat code, analogous to the continuous variable cat encod…

Entangling quantum logic gates in neutral atoms via the microwave-driven spin-flip blockade

Vikas Buchemmavari, Sivaprasad Omanakuttan, Yuan-Yu Jau +1

The Rydberg dipole-blockade has emerged as the standard mechanism to induce entanglement between neutral atom qubits. In these protocols, laser fields that couple qubit states to R…

Quantum computational advantage attested by nonlocal games with the cyclic cluster state

Austin K. Daniel, Yinyue Zhu, C. Huerta Alderete +7

We propose a set of Bell-type nonlocal games that can be used to prove an unconditional quantum advantage in an objective and hardware-agnostic manner. In these games, the circuit…
