Managing Editor\u2019s Note: According to Yahoo Finance, investing in quantum computing could \u201clead to life-changing returns\u2026 and make you the millionaire next door.\u201d That\u2019s why Jeff issued an urgent buy alert on his top three quantum computing stocks last week.<\/p>\n

Shares of NVIDIA have jumped 28,000% since Jeff first recommended it in February 2016. But if you missed out on that AI boom, you now have a second chance with the quantum computing revolution.<\/p>\n

The important thing is that you must act now. Before the end of this month, these stocks could explode higher. And there are just a few days left before Jeff\u2019s briefing on this opportunity goes offline. That\u2019s why it\u2019s vital that you watch this now. Go here to get the details before it\u2019s too late<\/a>.<\/p>\n

Then read on for more on the quantum breakthroughs happening as we speak\u2026<\/p>\n

\"\"<\/p>\n

It was October 2019 when Google first announced that it had achieved quantum supremacy.<\/p>\n

That was one of the biggest technology breakthroughs in history.<\/p>\n

Google\u2019s 54-quantum bit (qubit) superconducting semiconductor \u2013 Sycamore \u2013demonstrated that it could perform a complex calculation in 200 seconds that would have taken the world\u2019s most powerful classical supercomputer 10,000 years to calculate.<\/p>\n

It was a ridiculous feat.<\/p>\n

It was almost impossible to grok how a computer about the size of a refrigerator could run circles around the world\u2019s fastest supercomputer.<\/p>\n

However, as incredible as the feat was, the calculation that was performed had no real-world value.<\/p>\n

It wasn\u2019t solving anything useful. There wasn\u2019t any kind of scientific breakthrough\u2026<\/p>\n

It was just a calculation to demonstrate quantum supremacy.<\/p>\n

What followed was a painfully long wait for what came next.<\/p>\n

Google\u2019s Latest Quantum Breakthrough<\/p>\n

Google\u2019s quantum research organization is well known for keeping its developments close to the chest.<\/p>\n

We waited for years for a material update on the progress being made by Google\u2019s quantum team\u2026 more than five years to be exact.<\/p>\n

It wasn\u2019t until December 2024 that Google announced its new Willow 105-qubit quantum processor.<\/p>\n

Those five-plus years felt like an eternity, but it was worth the wait.<\/p>\n

The big news, however, wasn\u2019t about Google\u2019s new quantum processor\u2026<\/p>\n

But about its new quantum-error correction technology.<\/p>\n

What made Google\u2019s announcement at the time so significant was the introduction of a new error correction methodology.<\/p>\n

Specifically, Google demonstrated a system where as qubits increased, error rates decreased.<\/p>\n

This demonstrated a clear path towards a fault-tolerant quantum computer.<\/p>\n

And when you have that, you have a quantum computer that can achieve scientific breakthroughs.<\/p>\n

Most in the industry were thinking that the wait would be at least a couple of years before they heard anything from Google\u2019s quantum computing group, based on the last five-plus-year wait.<\/p>\n

That is why last week\u2019s announcement came as such a surprise.<\/p>\n

Almost as if on cue with our Quantum Week held here at Brownstone Research, Google dropped a research paper in Nature titled, \u201cObservation of constructive interference at the edge of quantum ergodicity<\/a>.\u201d<\/p>\n

The title might not seem like much\u2026<\/p>\n

But the breakthrough \u2013 which happened just 10 months after Google\u2019s December 2024 announcement \u2013 is in many ways even bigger.<\/p>\n

The headline was incredible, the kind that we\u2019re used to seeing when we think of quantum computers.<\/p>\n

Google\u2019s latest quantum processing chip \u2013 Willow \u2013 was able to demonstrate with its new algorithm \u2013 Quantum Echoes \u2013 that its quantum computer was capable of operating at speeds that are 13,000 times faster than the second-fastest classical supercomputer in the world \u2013 Frontier at Oak Ridge National Laboratory.<\/p>\n

Google\u2019s quantum computer completed the required calculations in 2.1 hours, when it would have taken Frontier 3.2 years to do the same.<\/p>\n

Like I mentioned, it\u2019s the kind of headline that we\u2019re used to reading about when it comes to quantum computing.<\/p>\n

But that\u2019s not what made the announcement such a big deal.<\/p>\n

A Quantum \u201cFirst\u201d<\/p>\n

What makes it so exciting is that the results of the calculation were verifiable.<\/p>\n

This is the first time in history that this has been accomplished, something that Google is referring to as quantum verifiability.<\/p>\n

Last week, one of our clever Bleeding Edge subscribers wrote in with an important and very relevant question\u2026<\/p>\n

The gist of it was, \u201cIf quantum computers can perform calculations that no supercomputer can perform, how can we know the answer is correct?\u201d<\/p>\n

I gave some perspective on some of the techniques that the quantum computing industry has been using to confirm that quantum computers are operating correctly in The Bleeding Edge \u2013 1984 Was Supposed to Be Fiction<\/a>.<\/p>\n

The relevant section is titled \u201cThe Methodology of the Unknown.\u201d<\/p>\n

It\u2019s a tricky problem to solve and one that is receiving a lot of research and development by those in the industry.<\/p>\n

And that\u2019s what makes last week\u2019s announcement by Google so significant.<\/p>\n

The quantum computing system shown above is capable of producing verifiable predications.<\/p>\n

There are two ways the verification can be performed:<\/p>\n

Any algorithm or calculation can be verified by another quantum computing system of similar performance.
\nOr an experiment can be conducted on the quantum computer, and then the results can be compared with any real-world system (for example, compared to a molecular structure, atomic interactions, or material properties).<\/p>\n

The experiment that Google conducted specifically involved how information spreads and interferes in a complex quantum computing system.<\/p>\n

This kind of environment is a chaotic system \u2013 or ergodic system (which is where the name of the research paper comes from).<\/p>\n

In quantum computing systems with a large number of qubits, the system becomes deeply entangled, resulting in a system that is far too complex for classical supercomputers to understand.<\/p>\n

And here\u2019s where Google\u2019s approach gets really interesting\u2026<\/p>\n

The Application Layer for Quantum Computing<\/p>\n

Google used something called an echo protocol, which is an exciting technique used to reverse the steps that are taken in a quantum computation.<\/p>\n

At a high level, here is what the team did:<\/p>\n

Run the computation on the quantum computer (i.e., forward in time)
\nIntroduce some small perturbation into the system
\nThen run the computation backward in time
\nWatch how the forward and backward computations interfere with one another.<\/p>\n

The interference between the forward and backward computations is not destructive. It actually contains hidden information that is impossible to see or calculate by classical supercomputers.<\/p>\n

While this all might sound esoteric, Google actually demonstrated a practical application of this approach applied to nuclear magnetic resonance (NMR) spectroscopy.<\/p>\n

We can think of NMR loosely like an MRI for measuring magnetic interactions between atomic nuclei. This is useful because it can reveal molecular structures.<\/p>\n

Because this method has the ability to verify the quantum computer\u2019s output, there are practical and valuable implications for chemistry, drug development, and materials research.<\/p>\n

A simple example of what this means is that the development of a new drug will be reduced to days rather than what it takes today \u2013 years.<\/p>\n

This announcement represents the application layer for quantum computing. For reference, the quantum processor is the hardware layer, and the quantum error correction is the software systems layer.<\/p>\n

It enables us to apply quantum computing to practical problems with verified results.<\/p>\n

That\u2019s why this is such a powerful development.<\/p>\n

It might feel natural to think that the next big breakthrough in quantum computing will be another year from now, but that\u2019s linear thinking.<\/p>\n

Quantum computing has already hit an exponential curve in technological development.<\/p>\n

That means that the next breakthrough will come that much faster \u2013 within the next 6-8 months, maybe sooner.<\/p>\n

This is both exciting and concerning.<\/p>\n

Scientific breakthroughs from the use of quantum computers will become abundant, but it also means we have far less time than we think to upgrade today\u2019s encryption technology\u2026 and, for that matter, blockchain technology.<\/p>\n

We may be OK for the next two years or so, but after 3 years of exponential growth in quantum computing, I\u2019m not comfortable assuming that there won\u2019t be a major threat.<\/p>\n

That\u2019s not a lot of time to upgrade the entire internet and harden blockchain technology to be resilient against quantum computing attacks.<\/p>\n

Time is short, which is why this is such an urgent matter and an incredible opportunity.<\/p>\n

Companies well-established in this space will see their businesses ignite and quickly become acquisition targets by larger tech companies.<\/p>\n

Here at Brownstone, we\u2019re always looking ahead, with an exponential mindset.<\/p>\n
