Adversarial guesswork with quantum side information
Baasanchimed Avirmed, Kaito Niinomi, M. Dall’Arno·Jun 22, 2023
The guesswork of a classical-quantum channel quantifies the cost incurred in guessing the state transmitted by the channel when only one state can be queried at a time, maximized over any classical pre-processing and minimized over any quantum post-p...
Efficient quantum image representation and compression circuit using zero-discarded state preparation approach
Md. Ershadul Haque, M. Paul, A. Ulhaq +1 more·Jun 22, 2023
Quantum image computing draws a lot of attention due to storing and processing image data faster than classical. With increasing the image size, the number of connections also increases, leading to the circuit complex. Therefore, efficient quantum im...
Hunting for Majoranas
A. Yazdani, F. von Oppen, B. Halperin +1 more·Jun 21, 2023
Over the past decade, there have been considerable efforts to observe non-abelian quasiparticles in novel quantum materials and devices. These efforts are motivated by the goals of demonstrating quantum statistics of quasiparticles beyond those of fe...
Entanglement Distribution in Satellite-Based Dynamic Quantum Networks
Alena Chang, Yinxin Wan, G. Xue +1 more·Jun 15, 2023
Low Earth Orbit (LEO) satellites present a compelling opportunity for the establishment of a global quantum information network. However, satellite-based entanglement distribution from a networking perspective has not been fully investigated. Existin...
Construction of Antisymmetric Variational Quantum States with Real Space Representation.
Takahiro Horiba, Soichi Shirai, H. Hirai·Jun 14, 2023
Electronic state calculations using quantum computers are mostly based on the second quantized formulation, which is suitable for qubit representation. Another way to describe electronic states on a quantum computer is based on the first quantized fo...
Information compression via hidden subgroup quantum autoencoders
Feiyang Liu, Ka Bian, Fei Meng +2 more·Jun 13, 2023
We design a quantum method for classical information compression that exploits the hidden subgroup quantum algorithm. We consider sequence data in a database with a priori unknown symmetries of the hidden subgroup type. We prove that data with a give...
Navigating the 16-dimensional Hilbert space of a high-spin donor qudit with electric and magnetic fields
Irene Fernández de Fuentes, T. Botzem, M. A. Johnson +11 more·Jun 12, 2023
Efficient scaling and flexible control are key aspects of useful quantum computing hardware. Spins in semiconductors combine quantum information processing with electrons, holes or nuclei, control with electric or magnetic fields, and scalable coupli...
Tunable quantum emitters on large-scale foundry silicon photonics
Hugo Larocque, M. A. Buyukkaya, C. Errando-Herranz +11 more·Jun 10, 2023
Controlling large-scale many-body quantum systems at the level of single photons and single atomic systems is a central goal in quantum information science and technology. Intensive research and development has propelled foundry-based silicon-on-insu...
Kerr-effect-based quantum logical gates in decoherence-free subspace
Fangfang Du, Gang Fan, Xueqin Ren·Jun 9, 2023
The decoherence effect caused by the coupling between the system and the environment undoubtedly leads to the errors in efficient implementations of two (or three) qubit logical gates in quantum information processing. Fortunately, decoherence-free s...
Low-temperature holographic screens correspond to Einstein-Rosen bridges
M. Javarone·Jun 9, 2023
Recent conjectures on the complexity of black holes suggest that their evolution manifests in the structural properties of Einstein-Rosen bridges, like the length and volume. The complexity of black holes relates to the computational complexity of th...
Quantum Wasserstein distance between unitary operations
