Continuous Symmetry Breaking in a Trapped-Ion Spin Chain

Lei Feng, Or Katz, Casey Haack +5

One-dimensional systems exhibiting a continuous symmetry can host quantum phases of matter with true long-range order only in the presence of sufficiently long-range interactions.…

Experimental Implementation of an Efficient Test of Quantumness

Laura Lewis, Daiwei Zhu, Alexandru Gheorghiu +11

A test of quantumness is a protocol where a classical user issues challenges to a quantum device to determine if it exhibits non-classical behavior, under certain cryptographic ass…

Demonstration of three- and four-body interactions between trapped-ion spins

Or Katz, Lei Feng, Andrew Risinger +2

Quantum processors use the native interactions between effective spins to simulate Hamiltonians or execute quantum gates. In most processors, the native interactions are pairwise,…

-body interactions between trapped ion qubits via spin-dependent squeezing

Or Katz, Marko Cetina, Christopher Monroe

We describe a simple protocol for the single-step generation of -body entangling interactions between trapped atomic ion qubits. We show that qubit state-dependent squeezing ope…

Interactive Protocols for Classically-Verifiable Quantum Advantage

Daiwei Zhu, Gregory D. Kahanamoku-Meyer, Laura Lewis +15

Achieving quantum computational advantage requires solving a classically intractable problem on a quantum device. Natural proposals rely upon the intrinsic hardness of classically…
