Quantum 7, 896 (2023). https://doi.org/10.22331/q-2023-01-13-896 Quantum algorithms designed for realistic quantum many-body systems, such as chemistry and materials, usually require a large number of measurements of the Hamiltonian. Exploiting different ideas, such as importance sampling, […]
Quantum 7, 895 (2023). https://doi.org/10.22331/q-2023-01-13-895 We propose a protocol to encode classical bits in the measurement statistics of many-body Pauli observables, leveraging quantum correlations for a random access code. Measurement contexts built with these observables […]
Quantum 7, 894 (2023). https://doi.org/10.22331/q-2023-01-13-894 This paper proposes and proves security of a QKD protocol which uses two-universal hashing instead of random sampling to estimate the number of bit flip and phase flip errors. This […]
Quantum 7, 893 (2023). https://doi.org/10.22331/q-2023-01-13-893 Quantum machine learning (QML) models based on parameterized quantum circuits are often highlighted as candidates for quantum computing’s near-term “killer application”. However, the understanding of the empirical and generalization performance […]
Insider Brief UNSW Sydney researchers say they’ve taken another step toward large-scale quantum computers. The research focuses on precisely controlling single electrons nestled in quantum dots that run logic gates. Critical Quote: “This is a […]
Every year, IBM announces a quantum programming challenge and awards prizes to those who can solve it best. This year IBM has presented the following challenge: Preparing quantum states lies at the heart of quantum […]
Deloitte is holding a quantum climate challenge that seeks to have participants use quantum computers to simulate materials that filter carbon dioxide out of the atmosphere to help reach the 2°C temperature rise goal for […]
Thirteen, 53 and 433. That’s the size of quantum computers in terms of quantum bits, or qubits, which has significantly grown in the last years due to important public and private investments and initiatives. Obviously, […]
Australian engineers have discovered a new way of precisely controlling single electrons nestled in quantum dots that run logic gates. What’s more, the new mechanism is less bulky and requires fewer parts, which could prove […]
A quantum harmonic oscillator—a structure that can control the location and energy of quantum particles that could, in the future, be used to develop new technologies including OLEDs and miniature lasers—has been made at room […]
