Looking ahead, Intel now produces up to five silicon chips a week, including up to 26 qubits of quantum chips. This achievement means that Intel has greatly increased the number of existing quantum devices, and is expected to steadily increase the qubits in the next few years. Intel's quantum Hardware Director, Jim Clarke, said in an interview that the technology currently used for small-scale production could eventually extend to more than 1000 qubits. Due to the limitation of expansion and contraction caused by temperature fluctuations, engineers can not simply expand the number of quantum bits on the chip.
At present, each wafer is composed of quantum dots and must be sectioning carefully so that each chip ends with an appropriate number of qubits. Due to defects and physical constraints, the completed chip may eventually have 3,7,11 or 26 qubits. No matter what type of quantum computation prevails, Intel's goal is to build a framework that can extend more than 1 million qubits. This will allow the use of the same basic structure, but the improved qubit Overtime, without having to return to the origin at every time a new quantum breakthrough occurs.
According to Clark, "1000 qubits in 5 years are not unreasonable." He compared the time between the first integrated circuit in the world and the Intel 4004 processor with only 2500 transistors. In quantum technology, Clark thinks Intel may reach 1 million qubits in 10 years, but he said he might be a bit optimistic about that.
One of the challenges that remains to be solved is the extreme cold temperatures required to operate quantum processors. Because the temperature needs to be as close as possible to zero, the performance of the quantum computer needs much higher than that of traditional silicon to make it cost effective. With the progress of technology, the usability will be improved rapidly.
