While quantum phenomena can be demonstrated using experiments such as the Double-Slit Experiment, certifying that a multi-qubit system is truly tapping into quantum mechanics is a challenge. It also becomes exponentially more difficult as the number of qubits in a quantum system increases.

John Clarke, Michel H. Devoret and John M. Martinis have been awarded the Physics Nobel Prize for their work on quantum mechanics. Here's what you need to know.

Scientists John Clarke, Michel Devoret and John Martinis won the 2025 Nobel Prize in Physics for "the discovery of macroscopic quantum mechanical tunnelling and energy quantization in an electric circuit,

The 2025 Nobel Prize in physics honors three quantum physicists—John Clarke, Michel H. Devoret and John M. Martinis—for their study of quantum mechanics in a macroscopic electrical circuit.

Paul Schnackenburg, our 1-person SOC Down Under, goes into the basics of quantum computing, what the potential risks are, what steps you can take to mitigate those risks, what others in the industry are doing and how you can adopt the recommendations outlined by several different governments.

In the 1980s, John Clarke, Michel Devoret and John Martinis demonstrated quantum effects in an electric circuit, an advance that underlies today’s quantum computers.

Rigetti Computing recently sold two of its quantum computing systems -- a positive step. JPMorgan has announced it will make major investments in the industry, among others. The total annual value for quantum computing usage could reach $15 billion by 2030.

The Trump administration is exploring equity-based investments in quantum computing firms like IonQ and Rigetti, signaling deeper government involvement in advancing U.S. tech innovation.

In effect, quantum mechanics does not just give you dice to play with ... Don Howard in Synthese, Vol. 86, No. 1, pages 123–141; January 1991. Freedom Evolves. Daniel C. Dennett. Viking, 2003. Laws, Causation and Dynamics at Different Levels.

Once fault tolerance is solved, IBM expects to scale its quantum computers up to 2000 quantum bits in 2033 and beyond. The company expects its quantum computers to have real-world applications in security, chemistry, machine learning, and other areas once this milestone is reached.

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean-field theory allows researchers to reduce many-body ...
