It sits inside the Josephson junction, the tiny circuit element at the heart of superconducting quantum bits, or qubits.
For much of the history of superconducting quantum computing, researchers had other limitations to overcome, including electromagnetic noise, quasiparticle losses and losses associated with wiring.
Devoret shared the 2025 Nobel Prize in Physics with John Clarke and John Martinis,a UCSB professor of physics, for experiments demonstrating macroscopic quantum mechanical tunneling and energy quantization in an electrical circuit, foundational work for today's superconducting quantum technologies.
Disorder only atoms wide A conventional Josephson junction sandwiches an insulating layer of aluminum oxide between two superconducting aluminum electrodes.
Princeton's Nathalie de Leon, who directs the institute, has noted that superconducting quantum researchers have relied on essentially the same junction technology for roughly 25 years.

Diraq is on a mission to make quantum computers practical enough to tackle problems beyond the reach of today's machines.
Many of these breakthroughs depend on understanding how atoms and molecules interact, which quickly becomes too complex for today's computers to model accurately.
AI changed what we can do with data; quantum computing will change what we can do with matter, molecules and materials.
It's quantum computers working alongside classical and AI systems, each doing what it does best.
Quantum computers create new knowledge instead, using qubits to simulate physical behaviour directly rather than approximate it.

But dismissing the heartbeat tale should not mean dismissing quantum magnetometry.
Demystifying Quantum Magnetometry Most people have cursory knowledge about magnetometry, which measures the strength and sometimes the direction of magnetic fields generated by electric currents and magnetized materials.
A magnetic field makes the aligned spins wobble, darkening the glass cell by the exact amount that field deflects them.
Operationalizing Quantum Magnetometry Quantum magnetometry reveals metal and movement from a distance and without emitting a signal that adversaries can detect much less dodge or jam.
Prescriptions Although physics binds performance on issues like clutter and noise filtering, the key barriers to fielding quantum magnetometry lie in procurement and assimilation.

This challenge motivates research into whether quantum computing approaches can learn useful patterns from limited symptom and risk-factor data.
The study, published in Discover Quantum Science, a Springer Nature journal, “Inferring lung cancer under limited learning data through gate-based and annealing-based quantum techniques,” provides a common framework for evaluating different quantum machine learning methods under the same data preparation and testing conditions.
“Our goal was to examine how different quantum learning approaches perform when the amount of training data is deliberately constrained,” said Munir.
The study examined two major approaches to quantum computing: quantum annealing and gate-based computing.
The authors acknowledge FAU and D-Wave for providing access to D-Wave’s quantum computing hardware.

3 min read The answer to one of the biggest questions in quantum computing might have been all around us this whole time: light.
If this finding is validated by further research and implementation, it could help move quantum computing closer to real life.
The research starts from an understanding that quantum computing, or quantum information processing, is something fundamentally different from the paradigms we have today.
There’s no general purpose quantum computer.
“While these effects have been explored in the context of nanophotonic systems and quantum sensors, their implications for multiphoton quantum information processing have yet to be investigated,” the team explains.

Titled ‘Transition to Post-Quantum Cryptography Standards,’ the report identifies existing quantum-vulnerable cryptographic standards and quantum-resistant standards designed to replace them.
Many applications include components that are based on standardized protocols and security technologies that will need to be revised to support using PQC algorithms.
Applications may also rely upon infrastructure components, such as public key infrastructures (PKIs), that would need to be updated to support the PQC algorithms before the applications themselves can migrate to using the PQC algorithms.
NIST’s transition schedule supports this risk-based approach of quantum-vulnerable public-key cryptography will be deprecated after 2030 and disallowed under NIST standards and guidelines after 2035.
He added that formal PQC standards have existed for two years now, but there is no one-size-fits-all way to implement them.
