Befriending the quantum computing disruption: Lessons from double-bracket quantum algorithms

In this talk we will explore what is likely to make up the disruption caused by quantum computing, how it will come about and when (or actually whether) it will happen. I will discuss the example of decyphering secrets safeguarded by the RSA protocol but will also look out to the potential revenue streams from quantum computing after migration to other cryptographic protocols. These will likely include applications in materials science, physics or general-purpose optimizations and each could lead to technological advances. I will describe how the geometry of the unitary group facilitated my work at NTU on developing optimization solvers in quantum computing and the lessons learned along the way. In brief, quantum computing has been maturing: its prodigious prospects remain exciting and at the same time we, as a community, have learned much more about the realities and requirements needed to realize practically useful quantum computations.

Quantum processing using QIBO

Let's look at the essential ingredients of the circuit model of a quantum computer, see how quantum gates build upon basic calculations typically covered in introductory quantum mechanics courses, explore how circuits made of quantum gates allow us to make sense of computations involving several qubits and finally get a taste for what it feels to design, compile and run algorithms performing quantum information processing. Two paradigmatic quantum circuits will be discussed: how to entangle a particular product state into a Bell state and the swap-test circuit for measuring overlaps between pure quantum states. All formulas will be accompanied with an online interactive python notebook implementing the examples using QIBO.
