Operating two exchange-only qubits in parallel
Mateusz T. Mądzik, Florian Luthi, Gian Giacomo Guerreschi +38
Semiconductors are among the most promising platforms to implement large-scale quantum computers, as advanced manufacturing techniques allow fabrication of large quantum dot arrays…
Fast photon-mediated entanglement of continuously-cooled trapped ions for quantum networking
Jameson O'Reilly, George Toh, Isabella Goetting +8
We entangle two co-trapped atomic barium ion qubits by collecting single visible photons from each ion through in-vacuo 0.8 NA objectives, interfering them through an integrated fi…
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,…
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…
Digital quantum simulation of NMR experiments
Kushal Seetharam, Debopriyo Biswas, Crystal Noel +8
Simulations of nuclear magnetic resonance (NMR) experiments can be an important tool for extracting information about molecular structure and optimizing experimental protocols but…
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…
Observation of measurement-induced quantum phases in a trapped-ion quantum computer
Crystal Noel, Pradeep Niroula, Daiwei Zhu +8
Many-body open quantum systems balance internal dynamics against decoherence from interactions with an environment. Here, we explore this balance via random quantum circuits implem…
Optimizing Stabilizer Parities for Improved Logical Qubit Memories
Dripto M. Debroy, Laird Egan, Crystal Noel +6
We study variants of Shor's code that are adept at handling single-axis correlated idling errors, which are commonly observed in many quantum systems. By using the repetition code…
Fault-Tolerant Operation of a Quantum Error-Correction Code
Laird Egan, Dripto M. Debroy, Crystal Noel +8
Quantum error correction protects fragile quantum information by encoding it into a larger quantum system. These extra degrees of freedom enable the detection and correction of err…
Quantum Gates on Individually-Addressed Atomic Qubits Subject to Noisy Transverse Motion
M. Cetina, L. N. Egan, C. A. Noel +5
Individual trapped atomic qubits represent one of the most promising technologies to scale quantum computers, owing to their negligible idle errors and the ability to implement a f…
Exploring More-Coherent Quantum Annealing
Sergey Novikov, Robert Hinkey, Steven Disseler +6
In the quest to reboot computing, quantum annealing (QA) is an interesting candidate for a new capability. While it has not demonstrated an advantage over classical computing on a…
