While many experts in the quantum industry are concerned about the hype surrounding the technology, some are suggesting quantum tech might not be hyped enough. According to one respected deep-tech investor, quantum computing is still underestimated and is only a few years away from commercial use.
Karthee Madasamy, founder of Silicon Valley venture fund MFV Partners, told Nikkei Asia he sees strong momentum in quantum computing, likening it to how ChatGPT surprised the world.
“People are going to underestimate [quantum computing] … It’s like ChatGPT,” he told Nikkei Asia. “Until ChatGPT, nobody was thinking about natural language … Now everybody’s like, ‘It’s going to kill this world.’”
Investor sees sector as ‘underestimated,’ has potential to break AI bottleneck.

For the first time, researchers transformed light into a quantum crystalline structure to create a “supersolid” that’s both solid and liquid at the same time. Here’s what that means, and why it’s such a big step forward.

Physicists are stuck on trying to figure out why gravity and quantum mechanics don’t get along. For almost 100 years now, they have been looking for a theory of quantum gravity to solve the problem. But one of the most general expectations of a quantization of gravity is that space also has quantum fluctuations. And a team of researchers from Caltech now says they’ve got a tabletop experiment which could find those fluctuations. Could this solve the problem? Let’s take a look.
Quantum entanglement, one of the strangest and most powerful aspects of physics, has just been taken to a new level with the use of metasurfaces.
Researchers have discovered a way to create quantum holograms, where entangled photons encode intricate information with unprecedented precision. By leveraging the properties of metasurfaces, they demonstrated control over entangled holographic letters, opening doors to secure quantum communication and even anti-counterfeiting technology.

However, inspired by daily life experiences in Southern California, I present a defense of indeterminism, countering the claim that everything is predetermined, while also exploring the ideas of cosmologists Raphael Bousso and Alan Guth.
Sabine Hossenfelder, a theoretical physicist, has argued in favor of superdeterminism, a theory that suggests the universe is deterministic and that our choices are predetermined.
According to her, the apparent randomness in quantum mechanics is an illusion, and the universe is actually a predetermined, clockwork-like system. She claims that if we knew enough about the initial conditions of the universe, we could predict every event, including human decisions.
Hossenfelder’s argument relies on the idea that the randomness in quantum mechanics is not fundamental, but rather a result of our lack of knowledge about the underlying variables. She suggests that if we could access these “hidden variables,” we would find that the universe is deterministic. However, this argument is flawed.
For example, consider the double-slit experiment, where particles passing through two slits create an interference pattern on a screen. Hossenfelder would argue that the particles’ behavior is predetermined, and that the apparent randomness is due to our lack of knowledge about the initial conditions. However, this ignores the fact that the act of observation itself can change the outcome of the experiment, a phenomenon known as wave function collapse.
A team of quantum computer researchers at quantum computer maker D-Wave, working with an international team of physicists and engineers, is claiming that its latest quantum processor has been used to run a quantum simulation faster than could be done with a classical computer.
In their paper published in the journal Science, the group describes how they ran a quantum version of a mathematical approximation regarding how matter behaves when it changes states, such as from a gas to a liquid—in a way that they claim would be nearly impossible to conduct on a traditional computer.
Over the past several years, D-Wave has been working on developing quantum annealers, which are a subtype of quantum computer created to solve very specific types of problems. Notably, landmark claims made by researchers at the company have at times been met with skepticism by others in the field.
