The trainability of photonic quantum circuits
Alexander Makarovskiy, Adam Taylor, Zhenghao Li +5
Variational quantum algorithms are a leading approach to near-term quantum computing, but their scalability can be limited by barren plateaus and the sampling cost of resolving sma…
Machine learning of quantum data using optimal similarity measurements
Zhenghao Li, Hao Zhan, Shana H. Winston +11
Quantum machine learning seeks a computational advantage in data processing by evaluating functions of quantum states, such as their similarity, that can be classically intractable…
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…
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…
Quantum error cancellation in photonic systems -- undoing photon losses
Adam Taylor, Gabriele Bressanini, Hyukjoon Kwon +1
Real photonic devices are subject to photon losses that can decohere quantum information encoded in the system. In the absence of full fault tolerance, quantum error mitigation tec…
Gaussian boson sampling validation via detector binning
Gabriele Bressanini, Benoit Seron, Leonardo Novo +2
Gaussian boson sampling (GBS), a computational problem conjectured to be hard to simulate on a classical machine, has been at the forefront of recent years' experimental and theore…
Reversing Lindblad Dynamics via Continuous Petz Recovery Map
Hyukjoon Kwon, Rick Mukherjee, M. S. Kim
An important issue in developing quantum technology is that quantum states are so sensitive to noise. We propose a protocol that introduces reverse dynamics, in order to precisely…
Fluctuation Theorems for a Quantum Channel
Hyukjoon Kwon, M. S. Kim
We establish the general framework of quantum fluctuation theorems by finding the symmetry between the forward and backward transitions of any given quantum channel. The Petz recov…
Clock-work trade-off relation for coherence in quantum thermodynamics
Hyukjoon Kwon, Hyunseok Jeong, David Jennings +2
In thermodynamics, quantum coherences - superpositions between energy eigenstates - behave in distinctly nonclassical ways. Recently mathematical frameworks have emerged to account…
