Quantum computing is often framed through extremes: either as an imminent disruption to every system, or as a technology too distant to matter. In our interview with Professor Giancarlo Gatti, we take a more grounded view: What primitives does quantum mechanics actually provide?

Giancarlo explains how quantum systems can support privacy-preserving communication, including user privacy and data privacy. We also cover Q-Day, RSA, post-quantum security, benchmarking, HHL, and why quantum should complement classical systems rather than replace them.

The full conversation is a grounded look at what quantum cryptography can actually enable, what is still missing, and how industry should think about the road ahead. Watch the full interview with Professor Giancarlo Gatti:

@Gatgian finally someone saying what needs to be said. the hype cycle around quantum has been exhausting honestly

@Gatgian i feel like quantum gets the same treatment as AI did a few years ago. everyone either panicking or dismissing it completely

@Gatgian quantum's promise isn't in being revolutionary but incremental augmenting existing systems with new maths

@Gatgian the extremes framing is so real. its either the end of encryption or its useless depending on who you ask

@Gatgian hmm like do most people even understand what a quantum primitive is before they start making predictions lol

@Gatgian lol so basically quantum twitter is just two guys yelling at each other from opposite ends of a spectrum 🤣

@Gatgian what primitives does quantum mechanics actually provide is such a good framing for this conversation. most people skip straight past that question

6,100-Qubit Processor Shatters Quantum Computing Record | David Nield, ScienceAlert Another major quantum computing record has been broken, and by a considerable margin: physicists have now built an array containing 6,100 qubits, the largest of its type and way above the thousand or so qubits previous systems contained. It's the work of scientists from the California Institute of Technology, who used cesium atoms as their qubits, trapping them in place with a complex system of lasers that acted as tweezers to keep the atoms as stable as possible. Qubits differ from the classical bits of traditional computers by exploiting what's known as a superposition: not just binary states of 1 or 0, but a spread of probabilities that allows for algorithms that can solve problems considered out of reach of conventional computing methods. Related: Quantum Advantage: A Physicist Explains The Future of Computers A lot of qubits will be needed to make quantum algorithms practical, however. One reason for these large arrays is error correction, which helps overcome the inherent fragility of the qubit by providing a surplus to double-check the machine's operation. "This is an exciting moment for neutral-atom quantum computing," says physicist Manuel Endres. "We can now see a pathway to large error-corrected quantum computers. The building blocks are in place." There was no single breakthrough that enabled this jump in qubit numbers, but rather a series of engineering advancements in many key areas – from the laser tweezers to the ultra-high (very low pressure) vacuum chamber. Stability has also been a problem for quantum computing systems. The innovations in this latest array kept qubits in a superposition state for almost 13 seconds – almost ten times longer than previous configurations had managed. What's more, individual qubits could be manipulated with 99.98 percent accuracy, establishing a significant benchmark in the programmability of quantum technology. "Large scale, with more atoms, is often thought to come at the expense of accuracy, but our results show that we can do both," says physicist Gyohei Nomura. "Qubits aren't useful without quality. Now we have quantity and quality." To make quantum computers a practical alternative to modern supercomputers, more qubits and even greater levels of stability will be required. Experts are tackling the problem from several different angles, which is why records for some types of quantum computer don't necessarily apply to others. Next, the researchers need to work on exploiting entanglement, which will enable the system to make the leap from storing information to actually processing it. Not too far in the future, we could be using these computers to discover new materials, matter, and fundamental laws of physics. "It's exciting that we are creating machines to help us learn about the Universe in ways that only quantum mechanics can teach us," says physicist Hannah Manetsch. Read more:
