Quantum fundamentals
What a qubit is, and what it is not
Quantum computers are often described as machines that try every answer at once. That picture is wrong, and the real one is more useful.
Noise, error correction and why logical qubits matter
Today’s quantum computers make mistakes far more often than classical ones. Error correction is how the field plans to fix that, and it changes how we should count qubits.
Quantum software
Why quantum programs need a language of their own
Qubits cannot be copied, measuring them changes them, and scratch qubits must be returned exactly as they were found. These rules are why Lucivant is developing qLuciv, a quantum programming language.
Trust and benchmarking
Quantum computing needs a common way to measure itself
Qubit counts, fidelities and “quantum advantage” are reported in different ways by different people. Until results are measured and reported consistently, buyers and researchers are comparing claims, not machines.
Why quantum results need to be checkable
As quantum computers move from the laboratory into real work, the question changes from “can it run?” to “how do we know the answer is right?”
Cybersecurity
Quantum computing and cybersecurity: getting ready for post-quantum cryptography
A large quantum computer would break the public-key cryptography that protects most of the internet. The replacements already exist, and the time to plan the move is now.
Entrepreneurship
Why I founded Lucivant Technologies: accountable quantum computing
Quantum computing will be adopted where its results can be relied on. That needs more than faster hardware, and it is the gap Lucivant Technologies Pty Ltd was founded to close.
Education
Closing the quantum skills gap
Quantum computing will need people who understand both the physics and the software. Many courses teach one or the other. Here is what I think good quantum education looks like.
