Teams around the world are racing to build the world’s first functioning quantum computer. The Centre of Excellence for Quantum Computation and Computer Technology (CQC2T), based at UNSW Sydney, leads the world in silicon-based architecture. This is the journey so far.
1. How Quantum Computers Will Change Our World
Why is the quest for quantum computers so important? Michelle Simmons, UNSW Scientia Professor and Director of the Centre of Excellence for Quantum Computation and Computer Technology (CQC2T) tells us why.
Crucial hurdle overcome for quantum computing (2015)
The world’s first calculation using two quantum bits in silicon has been demonstrated by a team of engineers at UNSW Australia.
The manufacturing techniques used are the same as those employed in today’s silicon chip industry, opening the way to ultra-powerful quantum computers.
Down to the Wire (2012)
The tiniest silicon conducting wire ever made takes us a step closer to the creation of a practical quantum computer. Developed by UNSW PhD student Bent Weber, the wire is 10,000 times thinner than a human hair.
Flip-flop qubits: a whole new quantum computing architecture
UNSW engineers have revealed a completely new design for quantum computing that they’re calling ‘flip-flop qubits’. The new chip design allows for a silicon quantum processor that can be scaled up without needing the precise placement of atoms required in other approaches. This new idea should make the eventual large-scale manufacture of quantum chips much cheaper and easier. Read More
How to build a quantum computer in silicon (2015)
Australian researchers have figured out a way to deal with errors in quantum computers, giving them the essential architecture that may help this team become the first to build a functioning quantum computer in silicon.
Landmark in quantum computing (2012)
A research team led by Australian engineers has created the first working quantum bit based on a single atom in silicon, opening the way to ultra-powerful quantum computers of the future.
New world record for silicon quantum computing (2014)
Research teams working in the same laboratories at UNSW Australia have found two different ways to solve a critical challenge and greatly accelerate the realisation of super powerful quantum computers.
The teams created two types of quantum bits, or “qubits” – the building blocks for quantum computers – that each perform quantum operations with accuracy above 99 percent.
Pinpointing qubits in a silicon quantum computer (2016)
Researchers from the Centre for Quantum Computation and Communication Technology (CQC2T) have solved a key challenge in the drive towards building a silicon-based quantum computer—one which could lead to more precise quantum logic operations.
Quantum computer coding in silicon now possible (2015)
A team of Australian engineers has proven – with the highest score ever obtained – that a quantum version of computer code can be written using two quantum bits in a silicon microchip. The advance removes lingering doubts that such operations can be made reliably enough to allow powerful quantum computers to become a reality.
Quantum data at the atom's heart (2013)
UNSW researchers have achieved a quantum breakthrough, turning the nucleus of an atom into a qubit or quantum bit – the building blocks of super powerful quantum computers of the future.
Single-atom transistor (2012)
In a remarkable feat of micro-engineering, UNSW physicists have created a working transistor consisting of a single atom placed precisely in a silicon crystal.
The “Dressed Qubit” - breakthrough in quantum state stability (2016)
Engineers from UNSW’s Centre for Quantum Computation & Communication Technology (CQC2T) have created a new quantum bit which remains in a stable superposition for 10 times longer than previously achieved, dramatically expanding the time during which calculations could be performed in a future silicon quantum computer.
Towards a quantum internet (2013)
A UNSW-led team of Australian researchers has achieved a breakthrough that brings the prospect of a network of super-fast quantum computers – connected via a quantum internet –closer to reality.
