The document discusses the development of a new type of qubit called the 'flip-flop qubit', which is designed to make quantum computers more scalable and affordable by using silicon-based technology. This qubit can maintain quantum entanglement over larger distances and is easier to integrate with traditional electronic circuits. It represents a significant advancement in the field of quantum computing, potentially allowing for the placement of millions of qubits in a compact design.

New type of qubit • New type of qubit – the building block of quantum computers – that they say will finally make it possible to manufacture a true, large- scale • Various type to make a Quantum Computer: – Some take up less space, but tend to be incredibly complex. – Others are simpler, but extremely large in size © Prof. Lili Saghafi , All Rights Reserved 3

Use circuits made of superconducting materials to detect quantum superpositions within the insanely slippery electrical currents. The advantage of these kinds of systems is their basis in existing techniques and equipment, making them relatively affordable and easy to put together. The cost is very high. © Prof. Lili Saghafi , All Rights Reserved 6

- 10. A new way to build Qubits • Based on coding information in both the nucleus and electron of an atom, the new silicon qubit, which is being called a ‘flip-flop qubit’, • This qubit can be controlled by electric signals, instead of magnetic ones. • It can maintain quantum entanglement across a larger distance than ever before, making it cheaper and easier to build into a scalable computer. © Prof. Lili Saghafi , All Rights Reserved 10

- 12. Flip-flop Qubit • The flip-flop qubit works by coding information on both the electron AND nucleus of a phosphorus atom implanted inside a silicon chip, and connected with a pattern of electrodes. • The whole thing is then chilled to near absolute zero and bathed in a magnetic field. © Prof. Lili Saghafi , All Rights Reserved 12

- 14. Entanglement and flip-flop qubit • The ‘entanglement’ between quantum bits – which is what makes quantum computers special • Whether too close, or too far apart these qubits • The flip-flop qubit is in the sweet spot between two extremes, offering true quantum entanglement across a distance of hundreds of nanometres. • This is a way to make silicon-based quantum computers scalable. © Prof. Lili Saghafi , All Rights Reserved 14
- 15. Qubit’s value • The qubit’s value is then determined by combinations of a binary property called spin – if the spin is ‘up’ for an electron while ‘down’ for the nucleus, the qubit represents an overall value of 1. Reversed, and it’s a 0. • The superposition of the spin-states is to be used in quantum operations. © Prof. Lili Saghafi , All Rights Reserved 15
- 16. In flip-flop • Researchers are able to control the qubit Using an electric field instead of magnetic signals two advantages. 1. It is easier to integrate with normal electronic circuits 2. qubits can communicate over larger distances. © Prof. Lili Saghafi , All Rights Reserved 16

- 18. To operate this qubit • To operate this qubit, we need to pull the electron a little bit away from the nucleus, using the electrodes at the top. • This create an electric dipole • These electric dipoles interact with each other over fairly large distances, a good fraction of a micron, or 1,000 nanometres. © Prof. Lili Saghafi , All Rights Reserved 18

- 20. flip-flop qubit • “This means we can now place the single-atom qubits much further apart than previously thought possible. So there is plenty of space to intersperse the key classical components such as interconnects, control electrodes and readout devices, while retaining the precise atom-like nature of the quantum bit.” “It’s easier to fabricate than atomic-scale devices, but still allows us to place a million qubits on a square millimetre.” Morello. © Prof. Lili Saghafi , All Rights Reserved 20
