Digital Quantum Simulation of the Schwinger Model and Symmetry Protection with Trapped Ions
Nhung H. Nguyen, Minh C. Tran, Yingyue Zhu +4
Tracking the dynamics of physical systems in real time is a prime application of digital quantum computers. Using a trapped-ion system with up to six qubits, we simulate the real-t…
Experimental Measurement of Out-of-Time-Ordered Correlators at Finite Temperature
Alaina M. Green, A. Elben, C. Huerta Alderete +6
Out-of-time-ordered correlators (OTOCs) are a key observable in a wide range of interconnected fields including many-body physics, quantum information science, and quantum gravity.…
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…
Experimental realization of para-particle oscillators
C. Huerta Alderete, Alaina M. Green, Nhung H. Nguyen +3
Para-particles are fascinating because they are neither bosons nor fermions. While unlikely to be found in nature, they might represent accurate descriptions of physical phenomena…
Cross-Platform Comparison of Arbitrary Quantum Computations
Daiwei Zhu, Ze-Pei Cian, Crystal Noel +14
As we approach the era of quantum advantage, when quantum computers (QCs) can outperform any classical computer on particular tasks, there remains the difficult challenge of how to…
Bounds on the recurrence probability in periodically-driven quantum systems
Tanmoy Pandit, Alaina M. Green, C. Huerta Alderete +2
Periodically-driven systems are ubiquitous in science and technology. In quantum dynamics, even a small number of periodically-driven spins leads to complicated dynamics. Hence, it…
Demonstration of Shor encoding on a trapped-ion quantum computer
Nhung H. Nguyen, Muyuan Li, Alaina M. Green +5
Fault-tolerant quantum error correction (QEC) is crucial for unlocking the true power of quantum computers. QEC codes use multiple physical qubits to encode a logical qubit, which…
Efficient, stabilized two-qubit gates on a trapped-ion quantum computer
Reinhold Blümel, Nikodem Grzesiak, Nhung H. Nguyen +5
Quantum computing is currently limited by the cost of two-qubit entangling operations. In order to scale up quantum processors and achieve a quantum advantage, it is crucial to eco…
