# QUANTUM TECH UPDATES: EPISODE 127

Hello quantum enthusiasts! Leo here from Quantum Tech Updates. We're recording on May 15th, 2025, and what a month it's been in quantum computing. The quantum era isn't just coming—it's already here.

Just a couple of weeks ago, on May 4th, TIME magazine published a fascinating piece confirming what many of us in the field have been saying: early adopters are already filing patents, building infrastructure, developing software platforms, and shaping standards that will define our quantum future.

But let me share something even more exciting that happened about six weeks ago. In late March—March 26th to be precise—researchers achieved a remarkable milestone using a 56-qubit quantum computer. For the first time, they experimentally demonstrated certified randomness generation. This might sound technical, but it's revolutionary.

Imagine trying to generate truly random numbers with your laptop. It's actually impossible—classical computers follow deterministic processes. But quantum computers operate on principles of quantum uncertainty, allowing them to produce randomness that's provably unpredictable. This recent breakthrough leveraged Quantinuum's System Model H2 quantum computer, which was upgraded to 56 trapped-ion qubits last June.

The significance? This quantum system outperformed existing classical methods by a factor of 100. To put this in perspective, think about the difference between a bicycle and a jet plane. Both are transportation methods, but they operate at fundamentally different speeds and capabilities. Similarly, classical bits are like simple on-off switches—they're either 0 or 1. But qubits can exist in a superposition of both states simultaneously, creating exponentially more processing potential.

What makes this development particularly noteworthy is that it represents one of the first practical, real-world applications of quantum advantage. Dr. Rajeeb Hazra, President and CEO of Quantinuum, described it as "a pivotal milestone that brings quantum computing firmly into the realm of practical, real-world applications."

The breakthrough wasn't achieved in isolation. It required collaboration between Quantinuum, JPMorganChase's Global Technology Applied Research team, and computing facilities at three major U.S. Department of Energy laboratories: Oak Ridge, Argonne, and Lawrence Berkeley.

I was talking with colleagues at a quantum computing conference in Waterloo last week, and the consensus is clear: 2025 is the year businesses need to become "quantum-ready." Microsoft made this declaration back in January, and we're seeing the evidence accumulate.

The quantum landscape is evolving rapidly across multiple fronts—we're seeing simultaneous advancements in scaling up qubit numbers, improving qubit fidelity, enhancing error correction, and developing quantum software and algorithms. My lab has been particularly focused on error correction, which remains one of the most significant challenges in building fault-tolerant quantum computers.

When I walk into our lab each morning and see the intricate laser systems maintaining quantum coherence in our prototype processor, I'm reminded of how far we've come. Just five years ago, many of these achievements seemed decades away. Now, we're witnessing the transition from theoretical potential to practical reality.

Looking ahead, the development of logical qubits will be crucial for tackling increasingly useful tasks. Think of logical qubits as the quantum equivalent of error-corrected memory in classical computing—they'll allow us to perform reliable computations despite the inherent fragility of quantum states.
