The previous record for entangled superconducting qubits was nine, but physicists have now experimentally shown that entanglement can exist between 10 qubits on a superconducting circuit. The 10-qubit state, the largest multi-qubit entangled state ever produced in a solid-state device, represents a significant advancement toward the development of massively parallel quantum computing.

In the brand-new setup, the scientists employed qubits made of minute aluminum pieces that they wired together and arranged in a circle around the central bus resonator.

The bus is an essential part of the system because it regulates the interactions that lead to entanglement between qubits.

Quantum tomography was used to calculate the likelihood of measuring every potential state of the system in order to gauge how strongly the qubits are entangled.

Future physicists hope to create a quantum simulator that could imitate the behavior of molecules and other quantum systems, making it possible to analyze these systems more effectively.


There are various kinds of physical operations that can be performed on 10 qubits
 A set of qubits is used by quantum logic gates, which are the fundamental components of a quantum circuit in a quantum computer.
 Coherence is lost during the irreversible quantum measurement process, which reveals information about the state of a single qubit.
 Sending the qubit, possibly as a component of a quantum network, across a quantum channel to a distant device or system.
 The fact that multiple qubits can display quantum entanglement is a key distinction between qubits and conventional bits.
