Conditions for implementing projective measurements through continuous monitoring
Therese Karmstrand, Franco Nori, Clemens Gneiting
Projective measurements are foundational for quantum physics in general and quantum information tasks in particular. However, their direct implementation is often not warranted. He…
Quantum Error Correction with Superpositions of Squeezed Fock States
Yexiong Zeng, Fernando QuijandrÃa, Clemens Gneiting +1
Bosonic codes, leveraging infinite-dimensional Hilbert spaces for redundancy, offer great potential for encoding quantum information. However, the realization of a practical contin…
Wave--particle transition and quantum Zeno effect in which-way experiments with a superconducting quantum processor
Shiyu Wang, Zhiguang Yan, Clemens Gneiting +3
Wave--particle duality demonstrates the peculiar nature of quantum mechanics. In which-way experiments, depending on the measurement scheme, a particle exhibits either wave-like or…
Quantum circuit complexity and unsupervised machine learning of topological order
Yanming Che, Clemens Gneiting, Xiaoguang Wang +1
Inspired by the close relationship between Kolmogorov complexity and unsupervised machine learning, we explore quantum circuit complexity, an important concept in quantum computati…
Variational Quantum Algorithm for Unitary Dilation
S. X. Li, Keren Li, J. B. You +4
We introduce a hybrid quantum-classical framework for efficiently implementing approximate unitary dilations of non-unitary operators with enhanced noise resilience. The method emb…
Cat-state-like non-Gaussian entanglement in magnon systems
Zeyu Zhang, Clemens Gneiting, Zheng-Yang Zhou +1
Magnons can serve as a bridge between spin, phonon, and photon systems, which renders them suitable for constructing hybrid systems. An important application of such hybrid systems…
