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,…
Programmable N-body interactions with trapped ions
Or Katz, Marko Cetina, Christopher Monroe
Trapped atomic ion qubits or effective spins are a powerful quantum platform for quantum computation and simulation, featuring densely connected and efficiently programmable intera…
-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…
