Journalists love a good headline. This one mentions teleportation. Beam me up Scotty, but not quite. Scientists tested using entangled qantum particles for communication along a 30klm fibre optic. Using a specific wavelength of light the two entangled particles, a pair of particles that communicate with each other specifically, were able to transmit and receive data. The benefit is the ability to communicate qantum information along with current forms of information on the existing networks we have. Excepting the last few klms of copper if that's what you have! Interesting as an indicator of continuing progress and investment in this area.

Here is a link that gives a fair starting background in Qantum computing, and what it is (Canadian investment broker). It provides some useful information but also reads as an ad for investing in the QTUM EFT. Nevertheless interesting. QTUM is targeting the hardware side of things so whilst there is some AI in there its the hardware side - chip development.

Its an area I am interested in, although I admit I don't fully understand the technology. It's a very early development space, so perhaps/probably unattractive to anyone except those with a longer investing view.

You can invest in individual stocks but figuring out which one is the future Apple, Microsoft or Amazon of course is pretty difficult/impossible. Disclosure - I have a small holding in this EFT as a place marker so I can stay in touch with state of play. I expect my kids will benefit rather than I.

I searched for discussions on this forum and didn't find much. I would be interested in others views about the subject. I'm not sure there are many local commercial opportunities.

Quantum computing is fascinating @Scot1963 and I'm a sucker for new tech. My high-level thoughts:

Quantum computers are crazy good at solving optimization problems, simulating quantum systems (e.g., for drug discovery and materials science), and breaking classical encryption through Shor’s algorithm. However, they’re not useful for general-purpose computing tasks.

The current state of the art with Willow is around 100 qubits, but better than IBMs 433 qubits because of better error correction, but these are still very noisy and not super reliable. Estimates suggest we’ll need around 1 million physical qubits to achieve fault-tolerant quantum computing. This means practical applications are likely still 5 -10 years (or more) away.

Also, quantum computers pose a threat to widely-used encryption methods like RSA and ECC, but quantum-resistant algorithms are already available. Switching to these algorithms will likely be gradual, akin to Y2K, giving governments and enterprises sufficient time to prepare.

I do think it's too early to be investable, however.

The integration of quantum computing into value chains remains pretty speculative. Early applications may focus on niches like logistics optimization, AI acceleration, and financial modeling. However, predicting how this will evolve across industries is challenging, particularly with the vast uncertainty surrounding timelines.

Like most emerging technologies, quantum computing is likely to see a tidal wave of startups, but only a fraction will become commercially viable. I'll definitely keep an eye on it, but the lesson from history is to wait until a few leaders emerge before allocating capital.
