With your friends Bob and Charlie, you’re visiting far-off lands when you meet Kettu. He suggests you play a game to determine which extreme sport you should try. Beware, the rules of this game are […]
Quantum 8, 1285 (2024). https://doi.org/10.22331/q-2024-03-14-1285 Thouless pumping represents a powerful concept to probe quantized topological invariants in quantum systems. We explore this mechanism in a generalized Rice-Mele Fermi-Hubbard model characterized by the presence of competing […]
Quantum 8, 1284 (2024). https://doi.org/10.22331/q-2024-03-14-1284 We show how to find all $k$ marked elements in a list of size $N$ using the optimal number $O(sqrt{N k})$ of quantum queries and only a polylogarithmic overhead in […]
Niccolo Somaschi, CEO of Quandela, is interviewed by Yuval Boger. Niccolo describes the company’s approach to quantum computing, emphasizing the use of photonics and semiconductor technologies to manipulate photonic qubits. He highlights Quandela’s focus […]
Quantum teleportation isn’t just science fiction; it’s entirely real and happening in laboratories today. But teleporting quantum particles and information is a far cry from beaming people through space. In some ways, it’s even more […]
Quantum 8, 1283 (2024). https://doi.org/10.22331/q-2024-03-14-1283 It is useful to have a criterion for when the predictions of an operational theory should be considered classically explainable. Here we take the criterion to be that the theory […]
Insider Brief QuSecure released a product designed to fortify existing Cisco router-to-router communications against emerging quantum threats. QuProtect leverages advanced crypto-agile post-quantum cryptography. The product is meant to protect critical network infrastructures for enterprises, government, […]
Quantum 8, 1282 (2024). https://doi.org/10.22331/q-2024-03-14-1282 In this article, we present a novel approach to investigating entanglement in the context of quantum computing. Our methodology involves analyzing reduced density matrices at different stages of a quantum […]
Quantum 8, 1281 (2024). https://doi.org/10.22331/q-2024-03-14-1281 Dynamically field-programmable qubit arrays (DPQA) have recently emerged as a promising platform for quantum information processing. In DPQA, atomic qubits are selectively loaded into arrays of optical traps that can […]
Quantum 8, 1280 (2024). https://doi.org/10.22331/q-2024-03-14-1280 Teleportation allows Alice to send a pre-prepared quantum state to Bob using only pre-shared entanglement and classical communication. Here we show that it is possible to teleport a state which […]
