Scientists have devised a small, reconfigurable quantum computer. All along, this nature is difficult to achieve. Although the paper did not show how to do this, the device is expected to be enlarged to a larger quantum computer. Related results recently published in "Nature."
Quantum computers solve some types of problems faster than traditional computers, but so far most quantum computers can perform limited tasks and are difficult to reconfigure. Shantanudebnath, a computer scientist at the University of Maryland, and colleagues created a new quantum computer consisting of just five bits of quantum information (qubits) that performs a series of different quantum algorithms, some of which take advantage of the quantum effects in one step A mathematical calculation, while a traditional computer requires several calculations to complete the calculation.
These qubits are stored in five ion traps, can be operated by laser, and can be reconfigured without changing the hardware. Researchers report that the system can perform basic operations with an accuracy of about 98%. They proposed that more quantum bits could be added to the system and that computing power could be added by connecting multiple modules.
