Input-Output Analysis of Quantum Dot SUPER Excitation
Johannes Kerber, Christoph Hotter, Helmut Ritsch +1
The Swing-UP of the quantum EmitteR population (SUPER) two-color pulsed excitation scheme allows for robust and close to 100\% excitation of a two-level quantum emitter using only…
Temporal-Mode Engineering for Multiplexed Microwave Photons and Mode-Selective Quantum State Transfer
Keika Sunada, Takeaki Miyamura, Kohei Matsuura +4
Quantum communication between distant superconducting qubits on separate chips using itinerant microwave photons has been studied to realize distributed quantum information process…
Plethysm is in #BQP
Matthias Christandl, Aram W. Harrow, Greta Panova +2
Some representation-theoretic multiplicities, such as the Kostka and the Littlewood-Richardson coefficients, admit a combinatorial interpretation that places their computation in t…
Engineering the non-Hermitian Su-Schrieffer-Heeger model with skin effects in Rydberg atom arrays
J. N. Bai, F. Yang, D. Yan +2
We propose and systematically analyze a practical scheme for implementing a one-dimensional non-Hermitian (NH) Su-Schrieffer-Heeger model using individually addressable Rydberg ato…
Implementation of the Quantum Fourier Transform on a molecular qudit with full refocusing and state tomography
Marcos Rubín-Osanz, Laura Bersani, Simone Chicco +7
Molecular spin qudits based on lanthanide complexes offer a promising platform for quantum technologies, combining chemical tunability with multi-level encoding. However, experimen…
Fault-tolerant quantum computation with constant overhead for general noise
Matthias Christandl, Omar Fawzi, Ashutosh Goswami
Fault-tolerant quantum computation traditionally incurs substantial resource overhead, with both qubit and time overheads scaling polylogarithmically with the size of the computati…
