Continuous-time noise mitigation in analogue quantum simulation
Gabriele Bressanini, Yue Ma, Hyukjoon Kwon +1
Analogue quantum simulators offer a promising route to explore quantum many-body dynamics beyond classical reach in the near term. However, their vulnerability to noise limits the…
Optimal Quantum Information Transmission Under a Continuous-Variable Erasure Channel
Adam Taylor, Michael Hanks, Hyukjoon Kwon +1
Quantum capacity gives the fundamental limit of information transmission through a channel. However, evaluating the quantum capacities of a continuous-variable bosonic quantum chan…
Photonic Hybrid Quantum Computing
Jaehak Lee, Srikrishna Omkar, Yong Siah Teo +4
Photons are a ubiquitous carrier of quantum information: they are fast, suffer minimal decoherence, and do not require huge cryogenic facilities. Nevertheless, their intrinsically…
Experimental demonstration of generalized quantum fluctuation theorems in the presence of coherence
Hui Li, Jie Xie, Hyukjoon Kwon +3
Fluctuation theorems have elevated the second law of thermodynamics to a statistical realm by establishing a connection between time-forward and time-reversal probabilities, provid…
Doubling Qubits in a Trapped-Ion System via Vibrational Dual-Rail Encoding
Minhyeok Kang, Wentao Chen, Hyukjoon Kwon +2
Vibrational modes of trapped ions have traditionally served as quantum buses to mediate internal qubits. However, with recent advances in quantum control, it has become possible to…
Quantum observables over time for information recovery
Gabriele Bressanini, Farhan Hanif, Hyukjoon Kwon +1
We introduce the concept of quantum observables over time (QOOT), an operator that jointly describes two observables at two distinct time points, as a dual of the quantum state ove…
