A team of researchers at University Grenoble Alpes and Centre of Excellence Quantum Technology has developed a single-quantum-dot heat valve. They have demonstrated gate control of electronic heat flow in a thermally biased single-quantum-dot junction. One of the key objectives was to demonstrate the feasibility of controlling the amount of heat that flows across a […]
Unexpected quantum behavior in insulators
Physicists at Princeton University have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum oscillation, is typically observed in metals rather than insulators, and its discovery offers new insights into our understanding of the quantum world. The observation of quantum oscillations has long been […]
Connecting ansatz expressibility to gradient magnitudes and barren plateaus
Researchers at Los Alamos National Laboratory proved a fundamental theorem for Quantum Neural Networks (QNNs), or more generally, for any parameterized quantum circuit (often called an “ansatz”). Parameterized quantum circuits serve as ansätze for solving variational problems and provide a flexible paradigm for programming NISQ computers. In Variational Quantum Algorithms (VQAs), a problem-specific cost function […]
Entangled error-protected qubits
Researchers from the University of Innsbruck have entangled two qubits distributed over several quantum objects and successfully transmitted their quantum properties. This marks an important milestone in the development of fault-tolerant quantum computers. For their experiment, the physicists use an ion-trap quantum computer with ten ions. Into these ions the logical qubits are encoded. Using a technique that […]
Pivotal discovery in quantum and classical information processing
Researchers in the Argonne National Laboratory and Pritzker School of Molecular Engineering have demonstrated a novel approach that allows real-time control of the interactions between microwave photons and magnons, potentially leading to advances in electronic devices and quantum signal processing. Microwave photons are elementary particles forming the electromagnetic waves that we use for wireless communications. Magnons are the […]
Pricing financial derivatives with exponential quantum speedup
Pricing financial derivatives, in particular European-style options at different time-maturities and strikes, is a relevant financial problem. The dynamics describing the price of vanilla options when constant volatilities and interest rates are assumed, is governed by the Black-Scholes model, a linear parabolic partial differential equation with terminal value given by the pay-off of the option […]
AION: A UK Atom Interferometry Observatory and Network
Searches for dark matter and the detection of gravitational waves in the Universe have been boosted by the announcement from the UKRI Science Technology and Facilities Council (STFC) of initial funding for the AION (Atom Interferometry Observatory and Network) project within its new Quantum Technologies for Fundamental Physics programme. The UK Quantum Technology Hub Sensors and Timing […]
Exploring the unanswered questions of our universe with quantum technologies
The UK Quantum Technology Hub Sensors and Timing is supporting a number of projects as part of the Quantum Technologies for Fundamental Physics programme, delivered by the Science and Technology Facilities Council (STFC) and the Engineering and Physical Sciences Research Council (EPSRC) as part of UKRI’s Strategic Priorities Fund. This is a new programme which aims to demonstrate how […]
Google and Boehringer Ingelheim partnership
Google’s Quantum AI division is teaming with pharmaceutical company Boehringer Ingelheim to develop new types of drugs using Quantum Computing. The idea is to research and develop quantum computing tech to do molecular dynamics simulations, or the study of how molecules and atoms move. The new partnership combines Boehringer Ingelheim’s leading expertise in the field of computer-aided […]
Germany: Bavaria State launches The Munich Quantum Valley
German Bavaria State has just announced the launch of the Munich Quantum Valley. This initiative is a merger of the Bavarian Academy of Sciences, the Fraunhofer Society, the Max Planck Society, the Ludwig Maximilians University of Munich and the Technical University of Munich to promote Quantum. The Munich Quantum Valley initiative would like to establish […]
