Silicon spin

Silicon spin

Silicon enjoys an unrivaled lead in human fabrication know-how and investment. Importantly, in its isotopically purified form, it is an ideal neutral material to host sensitive spin qubits. Proponents emphasise the potential of this technology to deliver chip-scale solutions where some other approaches would require ‘building-size’ machines. But spin quibts are delicate. Nanofabricating the right…

NV diamonds

NV diamonds

Our ability to fabricate in diamond has undergone a transformation that is perhaps not fully appreciated outside of the specialist community. Diamond is another material well suited to hosting qubits. Point defects in a diamond lattice act in many ways like isolated atoms and can be used to form qubits. Nitrogen-vacancy colour centres are widely…

Phontonics

Photonic

Light is the first system where humans observed quantum phenomena and remains in many ways the best understood. Conventionally driven investment in silicon photonics has now transformed our ability to engineer light in compact devices. Photons are naturally immune to many conventional forms of noise and most operations can already be completed with very high…

Neutral atoms

Neutral atoms

Neutral atoms can be confined in 2D arrays and 3D lattice structures by laser tweezers. Because of this natural ability to mimic systems of interest, they have long been considered a leading platform for analogue quantum simulation. However recent progress in demonstrating long-range 2Q gates across such structures have drawn attention to their potential as…

Topological qubits

Topological qubits

We don’t worry about errors in conventional computing chips because the digital transistor has hardware error correction built in. That’s why transistors replaced valves, unlocking the digital revolution. The idea behind topological qubits is to repeat this trick. Topological qubit proponents often use the analogy of tying a knot in a piece of string. The…

dilution fridge

Control and measurement plane

As one of the first quantum platforms to start to significantly scale-up, superconducting qubit platforms have been first to face a series of control plane challenges. These are complicated by the need to work down to extreme cryogenic temperatures. Pioneers face challenges across cryogenics, control electronics and control software. Cryogenics The first challenge for many…

Quantum safe cryptography – the big picture

Recently updated advice on quantum security technologies from the UK NCSC is bluntly sceptical about the promised benefits of quantum key distribution. This seems at odds with the scramble of governments around the world to promote the development of quantum networking technologies. Who is right? Future large scale quantum computers will one day bring many…

Quantum software – beneath the quantum hype

Commercial activity around quantum computing has risen to fever pitch over the last year. Many point to the traditional cycle of hype and consolidation in tech markets. Some have become quick to call ‘bullshit’ much of the activity at the current commercial frontier. Others predict a coming quantum winter. How can investors and early adopters…
