Silicon-based quantum computer has arrived as Silicon-based technology is a late event in the quantum computing world lingering behind other methods. For the first time scientists have solved simple algorithms on a silicon-based quantum computer.
The computer entails only two quantum bits or qubits so it can carry out only elementary calculations. However, the demonstration is unparalleled says quantum physicist Jason Petta of Princeton University. Petta and colleagues describe engendering silicon qubits collaborate with light in another paper. That achievement could finally permit silicon qubits to impart from conflicting sides of the chip, a prerequisite for scaling the computers up.
Scientists want to create a quantum computer that can compute complex calculations intractable for standard computers. Quantum computers made of superconducting materials, for example, have reportedly been made with up to 50 qubits.
But silicon qubits may have preference such as capability to maintain their quantum property for a longer period of time than other types of qubits. Also companies such as Intel are hitherto proficient at working with silicon as the material is utilized in conventional computer chips. Researchers look forward to make use of that ability, possibly permitting the computers to scale up more speedily. Vandersypen, of QuTech at Delft University of Technology in the Netherlands, and his colleagues have collaborated with Intel on some of their work.
In regular computers units of information called bits can be set to either 0 or 1. But qubits can occur in a oblivion between 0 and 1 known as quantum superposition. To generate silicon qubits scientists strategize a mono electron in a tiny bit of silicon called a quantum dot. The merit of qubit 0, 1 or a superposition hangs on the direction of the electron’s spin, a quantum property similar to the spinning of the top.
