Introduction Overall, the US is one of the leading players in the research, investment and private sector in quantum tech globally. Going back a few decades, the US was the dominant player until China made […]
Quantum 7, 978 (2023). https://doi.org/10.22331/q-2023-04-13-978 Extracting classical information from quantum systems is an essential step of many quantum algorithms. However, this information could be corrupted as the systems are prone to quantum noises, and its […]
Quantum 7, 977 (2023). https://doi.org/10.22331/q-2023-04-13-977 Simulating many-body quantum systems is a promising task for quantum computers. However, the depth of most algorithms, such as product formulas, scales with the number of terms in the Hamiltonian, […]
This article on Chinese Quantum Companies and National Strategy was written from information and data on The Quantum Insider’s proprietary market intelligence platform and premium report: Quantum Technology in China. Introduction A Brief Overview of […]
Quantum 7, 976 (2023). https://doi.org/10.22331/q-2023-04-13-976 Quantum homomorphic encryption, which allows computation by a server directly on encrypted data, is a fundamental primitive out of which more complex quantum cryptography protocols can be built. For such […]
Quantum 7, 975 (2023). https://doi.org/10.22331/q-2023-04-13-975 Mapping fermionic operators to qubit operators is an essential step for simulating fermionic systems on a quantum computer. We investigate how the choice of such a mapping interacts with the […]
Insider Brief ChatGPT-4 registered a score that’s equivalent of a B in Scott Aaronson’s Introduction to Quantum Information Science final exam. The course is an honors upper-level undergraduate course at the University of Texas-Austin. ChatGPT-4 […]
Quantum 7, 974 (2023). https://doi.org/10.22331/q-2023-04-13-974 We analyze the barren plateau phenomenon in the variational optimization of quantum circuits inspired by matrix product states (qMPS), tree tensor networks (qTTN), and the multiscale entanglement renormalization ansatz (qMERA). […]
We are looking for a highly motivated student to do a PhD at the Quantum Computation Structures Team (QuaCS) at the Laboratoire Méthodes Formelles (LMF) in Paris-Saclay. PhD Opening at QuaCS Submitted by encorz on […]
Some classical computers have error correction built into their memories based on bits; quantum computers, to be workable in the future, will need error correction mechanisms, too, based on the vastly more sensitive qubits. Click […]
