ML-Powered FPGA-based Real-Time Quantum State Discrimination Enabling Mid-circuit Measurements
Neel R. Vora, Yilun Xu, A. Hashim +11 more·Jun 27, 2024
Similar to reading the transistor state in classical computers, identifying the quantum bit (qubit) state is a fundamental operation to translate quantum information. However, identifying quantum state has been the slowest and most susceptible to err...
Stark control of plexcitonic states in incoherent quantum systems
Hira Asif, Ramazan Sahin·Jun 27, 2024
In this study, we demonstrate the coherent control of plexcitonic modes in (i) off-resonant and (ii) resonant coupled plasmon-emitter systems through the optical Stark effect (OSE). By leveraging the Stark shift in degenerate energy eigenstates of tw...
YAQQ: yet another quantum quantizer design space exploration of quantum gate sets using novelty search
Aritra Sarkar, Akash Kundu, M. Steinberg +5 more·Jun 25, 2024
The standard model of quantum computation is based on quantum circuits, where the number and quality of the quantum gates composing the circuit influence the runtime and fidelity of the computation. The fidelity of the decomposition of quantum algori...
Low-overhead transversal fault tolerance for universal quantum computation
Hengyun Zhou, Chen Zhao, M. Cain +7 more·Jun 25, 2024
Fast, reliable logical operations are essential for realizing useful quantum computers1, 2–3. By redundantly encoding logical qubits into many physical qubits and using syndrome measurements to detect and correct errors, we can achieve low logical er...
Visualizing Quantum States: A Pilot Study on Problem Solving in Quantum Information Science Education
Jonas Bley, Eva Rexigel, Alda Arias +8 more·Jun 24, 2024
In the rapidly evolving interdisciplinary field of quantum information science and technology, a major obstacle is the need to understand advanced mathematics to solve complex problems. Current findings in educational research suggest that incorporat...
Can quantum computers do nothing?
Alexander Nico-Katz, Nathan Keenan, John Goold·Jun 24, 2024
Quantum computing platforms are subject to contradictory engineering requirements: qubits must be protected from mutual interactions when idling (‘doing nothing’), and strongly interacting when in operation. If idling qubits are not sufficiently prot...
Validity condition for high-fidelity digitized quantum annealing
Alan C. Santos·Jun 24, 2024
Digitizing an adiabatic evolution is a strategy able to combine the good performance of gate-based quantum processors with the advantages of adiabatic algorithms, providing then a hybrid model for efficient quantum information processing. In this wor...
Fault-tolerant embedding of quantum circuits on hardware architectures via swap gates
