Physicists propose a quantum–optomechanical solution to dark-matter detection
An interdisciplinary collaboration between condensed-matter, quantum-optics and particle physicists has the potential to crack the search for low-mass dark matter. The proposed quantum detector builds on EQUS studies of elementary excitations in superfluid helium and advances in opto-mechanics.
Led by EQUS Research Fellow Dr. Chris Baker (UQ), study proposes direct detection of low-mass dark matter via its interactions with superfluid helium confined in an optomechanical cavity.
“Optomechanical dark matter instrument for direct detection” was published in Physical Review D in August 2024.
Quantum Scientists Just Made a Major Breakthrough Using 31 Superconducting Qubits
Scientists have achieved unprecedented control over quantum transport using a 31-qubit superconducting processor, opening new possibilities for next-generation electronics and thermal management. This approach allows researchers to observe and manipulate quantum particles with extraordinary precision, potentially revolutionizing how we develop future technologies.
The research, led by teams from Singapore and China, marks a significant advance in understanding how particles, energy, and information flow at the quantum level. This breakthrough could accelerate development of more efficient nanoelectronics and thermal management systems.
Learn Quantum Physics More Easily With This Breakthrough Approach
A team of physics educators from Italy, Hungary, Slovenia, and Germany is pioneering a new approach to teaching quantum physics in schools. Traditional classroom methods have typically emphasized the history and origins of quantum physics, which can often create challenges for learners.
The researchers, including physics education specialist Professor Philipp Bitzenbauer from Leipzig University, focus on qubits—two-state systems that are both the simplest and most crucial quantum systems, capable of describing many situations. Mastering the control and manipulation of these qubits is fundamental to advancing modern quantum technologies.
According to Bitzenbauer, until now there have been no empirical studies of the effectiveness of these approaches using two-state systems in developing conceptual understanding in learners. There is also a lack of scientific research on the specific advantages and disadvantages for learning of different teaching approaches based on two-state systems.
Emergence of steady quantum transport in a superconducting processor
