You either have to overthrow quantum mechanics(good luck), or you have to use qubits.
For instance, one can use the controlled NOT gate and the Walsh- Hadamard gate to entangle two qubits.
For now, there are two leading approaches: trapped ions and superconducting qubits.
This principle, which Einstein referred to as“spooky action at a distance,” allows the qubits to be controlled for the purposes of computation and communication.
Rigetti is also making the new quantum computer- which can handle 19 quantum bits, or qubits- available through its cloud computing platform, called Forest.
Importantly, it allows quantum bits(or‘qubits')- the basic unit of information in a quantum computer- to be placed hundreds of nanometers apart and still remain coupled.
Improvements to error mitigation and to the quality of qubits are our focus for making quantum computing systems useful for practical applications in the near future.
The main obstacle to using neutral atoms as qubits has been that, unlike ions, they experience very weak forces and are not easily held in place.
In“A blueprint for demonstrating quantum supremacy with superconducting qubits”, we illustrate a blueprint towards quantum supremacy and experimentally demonstrate a proof-of-principle version for the first time.
The first quantum computer capable of implementing it appeared in 1998, but the first scalable version didn't appear until 2017, and even then it worked with only three qubits.
In“A blueprint for demonstrating quantum supremacy with superconducting qubits”(arXiv here), we illustrate a blueprint towards quantum supremacy and experimentally demonstrate a proof-of-principle version for the first time.
Rami Barends and Alireza Shabani, quantum electronics engineers at Google, explain that controllability is the key, and have run experiments using nine qubits in conjunction with 1,000 logic gates.
IBM, Google and a number of academic labs have chosen relatively mature hardware, such as loops of superconducting wire, to make quantum bits(qubits).
To produce stable qubits, one promising approach is to use superconducting circuits, most of which operate on the basis of the Josephson effect.
A new computer constructed by Shantanu Debnath and colleagues is made up of just five bits of quantum information(qubits) and is shown to perform a number of different quantum algorithms.
Note that while each sub-group of eight qubits is tightly linked to its adjacent partners, the blocks themselves connect in far fewer places.
We made these qubits in silicon chips, similar to what's used in classical computer processes,” study author Thomas Watson from TU Delft in the Netherlands told me.
Although researchers have yet to achieve quantum supremacy, Google thinks it can be demonstrated with 49 qubits, a circuit depth exceeding 40, and a two-qubit error below 0.5 percent.
At the core is a phosphorus atom, from which Morello's team has previously built two functional qubits using an electron and the nucleus of the atom.
The analogy I use to describe how a QC program works is that multiple qubits interact like the waves generated by throwing a handful of small floating balls into a pool of water.
