One of the biggest limitations of quantum quantum computing is the “no cloning” theorem, which says you cannot copy a quantum state without destroying the original. If you could copy quantum states without harming the original, much of the error-correcting complications in quantum computing could be avoided. Luckily, in a recent paper, physicists have demonstrated that there’s a way around the “

Since the early days of quantum physics, some scientists have believed that there’s a link between quantum mechanics and consciousness. While most researchers don’t think this idea holds water, a few have published papers about how phosphate molecules in the brain could link consciousness to quantum physics. Let’s take a look.

When you try to combine quantum physics with Einstein’s theories, you quickly run into some pretty serious problems. The biggest is that causality – the order in which events occur – becomes uncertain as the rest of quantum physics. A group of physicists have leveraged that uncertainty, and are now claiming that they can send messages to the past using quantum mechanics. It’s not as crazy as it

To this day, researchers don’t fully understand quantum physics. But in a new paper, physicists from MIT say that that’s okay – because the phenomena we use quantum physics to explain can actually be understood using classical physics. Really? Let’s take a look.

Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated: Before we end, let’s now briefly talk about the birth of quantum information science, a pivotal shift that began in the 1990s. This is the era when researchers...

Comment on PBS Space Time video PBS Space Time produces some very good videos on the foundations of quantum mechanics (QM), so let me comment on their video What If Physics IS NOT Describing Reality to provide (crucial) missing information. This comment pertains only to the first 9 min of the video, i.e., it has...
