Quantum solutions are typically evaluated in terms of performance, efficiency, speedup or the number of qubits — but not energy consumption. Yet quantum computing comes at a high energy cost. To make sure quantum computing is developed energy-efficiently, it is essential to optimize the design of the circuit, and pay attention to aspects such as the circuit layout and how the execution is done on the quantum computer.
Like everyone else, scientists often know how to work in a more sustainable way — but choose not to. How can art help bridge the gap between knowledge and motivation?
Shaurya Aarav introduces a quantum imaging method that uses a high-resolution camera to speed up imaging acquisition while retaining correlation information.
Yertay Zhiyenbayev recounts how a 2020 paper that demonstrated isolated colour centres in siilicon for use in quantum optics inspired him to pursue this area of research.
This International Workers’ Day, we reflect on the role of scientists as workers and call on our readers to collaborate in their communities to improve working conditions for scientists.
As quantum technologies attract more and more funding, Christophe Couteau and Snežana Lazić argue for a clear and accessible definition of the label ‘quantum’. This would help public and private investors to make the right choices.
The Metre Convention was signed in May 1875, bringing international agreement on how to measure accurately and consistently — a consensus that was essential for trade, industrialization and scientific progress. 150 years later, how does the metrology community continue this tradition?
The UK’s quantum strategy prioritizes quantum sensing, but hiring trends focus on quantum computing and communication. To meet targets, the UK must realign hiring and education with its immediate needs.
Despite its benefits, globalized science also has problems, including asymmetric data sharing. Understanding the origin of these imbalances can help mitigate their long-term impacts.
To avoid a replication crisis in physics, physicists need to understand how ever-changing social forces shape scientific practice — and even the underlying notions of replicability and objectivity.
There is a natural though unexpected resonance between the concept of intersectionality — the simultaneous and compounded impact of two or more axes of discrimination — and that of emergence in physics.
The boundaries between science and pseudoscience are not always clear cut, as topics move in and out of the culturally accepted core of science. Rather, science needs to be judged on the merits of its methodology.
The way you were taught quantum mechanics depends on when you were a student; pedagogical approaches over the last century have been driven by social and political trends. Physicist and historian, David Kaiser, charts how the emphasis of quantum education has oscillated between philosophy and practicality.
