A New Quantum Paradox Throws The Foundations Of Observed Reality Into Question

If a tree falls in a forest and no one is there to hear it, does it make a sound? Perhaps not, some say. And if someone is there to hear it? If you think that means it obviously did make a sound, you might need to revise that opinion. We have found a new paradox in quantum mechanics – one of our two most fundamental scientific theories, together with Einstein’s theory of relativity – that throws doubt on some common-sense ideas about physical reality. Quantum mechanics vs common sense Take a look at these three statements: When someone observes…

Google And IBM Are At Odds Over ‘Quantum Supremacy’ – An Expert Explains What It Really Means

Google claims to have demonstrated something called “quantum supremacy”, in a paper published in Nature. This would mark a significant milestone in the development of a new type of computer, known as a quantum computer, that could perform very difficult calculations much faster than anything possible on conventional “classical” computers. But a team from IBM has published their own paper claiming they can reproduce the Google result on existing supercomputers. While Google vs. IBM might make a good story, this disagreement between two of the world’s biggest technology companies rather distracts from the real scientific and technological progress behind both…

Why Are Scientists So Excited About A Recently Claimed Quantum Computing Milestone?

A quantum computer may have solved a problem in minutes that would take the fastest conventional supercomputer more than 10,000 years. A draft of a paper by Google researchers laying out the achievement leaked in recent days, setting off an avalanche of news coverage and speculation. While the research has not yet been peer-reviewed – the final version of the paper is expected to appear soon – if it all checks out it would represent “the first computation that can only be performed on a quantum processor”. That sounds impressive, but what does it mean? Quantum computing: the basics To…

What Is Quantum Machine Learning And How Can It Help Us?

Artificial intelligence refers, among other things, to machines’ capacity to demonstrate some degree of what humans consider “intelligence”. This process is being driven by the rapid advancement of machine learning: getting machines to think for themselves rather than pre-programming them with an absolute concept. Take image recognition. Humans excel at this task, but it’s proved difficult to simulate artificially. Training a machine to recognise a cat doesn’t mean inputting a set definition of what a cat looks like. Instead, many different images of cats are inputted; the aim is that the computer learns to distil the underlying “cat-like” pattern of…
