Quantum dot technique improves multi-photon state generation
A photonics research group co-led by Gregor Weihs of the University of Innsbruck has developed a new technique for generating multi-photon states from quantum dots that overcomes the limitations of conventional approaches. This has immediate applications in secure quantum key distribution protocols, where it can enable simultaneous secure communication with different parties.
Quantum dots—semiconductor nanostructures that can emit single photons on demand—are considered among the most promising sources for photonic quantum computing. However, every quantum dot is slightly different and may emit a slightly different color. This means that to produce multi-photon states, we cannot use multiple quantum dots.
Usually, researchers use a single quantum dot and multiplex the emission into different spatial and temporal modes, using a fast electro-optic modulator. The technological challenge is that faster electro-optic modulators are expensive and often require very customized engineering. To add to that, they may not be very efficient, which introduces unwanted losses into the system.
US finds missing particle that makes quantum computing fully possible
Researchers at the University of Southern California (USC) in the US turned to an often overlooked particle for storing and processing quantum information to overcome the fragility of quantum computers and make them more universal in the near future.
Positioning one such particle in a quantum computer can help overcome errors in quantum computing, a university press release said.
The age of quantum computing promises computations at speeds that will make even the fastest supercomputers of today appear like snails. These computers leverage quantum properties of materials to store information in quantum bits or ‘qubits’
David Furman: How Microgravity Accelerates Aging & What It Teaches Us About Longevity | LSD 2025
In this Longevity Summit Dublin 2025 talk, Dr. David Furman (Buck Institute for Research on Aging) reveals how space medicine is becoming a powerful model for studying accelerated aging. From NASA collaborations to organoid experiments in simulated microgravity, Dr. Furman shows how heart, brain, and immune organoids age up to 10 years in just 24 hours — and how this can accelerate drug discovery for neurodegeneration, cardiovascular disease, and immune decline. Learn how microgravity research can predict your biological future and identify interventions to slow or reverse aging.

Russia’s plasma engine spacecraft could reach Mars in just 30 days
Rosatom scientists have announced the development of a plasma electric rocket engine that they claim could send spacecraft to Mars in just one to two months.
As reported by Russia’s Izvestia newspaper, unlike traditional rocket engines that rely on fuel combustion, this innovative propulsion system utilizes a magnetic plasma accelerator and promises to reduce interplanetary travel time significantly.
