Magic-Induced Computational Separation in Entanglement Theory
Andi Gu, Salvatore F. E. Oliviero, L. Leone·Mar 28, 2024
Entanglement serves as a foundational pillar in quantum information theory, delineating the boundary between what is classical and what is quantum. The common assumption is that a higher degree of entanglement corresponds to a greater degree of “quan...
Lindblad-like quantum tomography for non-Markovian quantum dynamical maps
S. Varona, Markus Muller, A. Bermudez·Mar 28, 2024
We introduce Lindblad-like quantum tomography (LℓQT) as a quantum characterization technique of time-correlated noise in quantum information processors. This approach enables the estimation of time-local master equations, including their possible neg...
On the feasibility of quantum teleportation protocols implemented with silicon devices.
Junghee Ryu, Hoon Ryu·Mar 28, 2024
With recent experimental advancements demonstrating high-fidelity universal logic gates and basic programmability, silicon-based spin quantum bits (qubits) have emerged as promising candidates for scalable quantum computing. However, implementation o...
Efficient generation of multi-partite entanglement between non-local superconducting qubits using classical feedback
A. Hashim, Ming Yuan, P. Gokhale +8 more·Mar 27, 2024
Quantum entanglement is one of the primary features which distinguish quantum computers from classical computers. In gate-based quantum computing, the creation of entangled states or the distribution of entanglement across a quantum processor often r...
Broadband and fabrication-tolerant 3-dB couplers with topological valley edge modes
Guo-Jing Tang, Xiaodong Chen, Lu Sun +10 more·Mar 25, 2024
3-dB couplers, which are commonly used in photonic integrated circuits for on-chip information processing, precision measurement, and quantum computing, face challenges in achieving robust performance due to their limited 3-dB bandwidths and sensitiv...
Generation of Genuine Multipartite Entangled States via Indistinguishability of Identical Particles
Kobra Mahdavipour, Farzam Nosrati, S. Sciara +2 more·Mar 25, 2024
Indistinguishability of identical particles is a resource for quantum information processing and has been utilized to generate entanglement from independent particles that spatially overlap only at the detection stage. Here, we introduce a controllab...
