Quantum computing stocks have become one of the most desirable and volatile prospects for investors and speculators. Operating far from the spotlight, in the Ness Ziona Science Park, Quantum Art is the only Israeli company building an end-to-end quantum computer. The company plans to launch a powerful computer next year with a performance outstripping that of Nvidia's strongest supercomputers. Just two months ago, Quantum Art acquired a new backer: US investment fund Bedford Ridge Capital, which led a $140 million financing round by the Israeli company. Tomorrow's quantum computers will be extraordinarily powerful, taking only seconds or minutes for calculations that existing computers take weeks or years to perform. They will accomplish this through a tiny processing unit in quantum computers called a "qubit." If the Quantum Art founders' plans work out, the quantum computer to be launched late next year will contain a microchip of up to 100 logical qubits - double the maximum computing power of the current strongest supercomputers of Nvidia and HP. Efficient technology The lively interest that Quantum Art is arousing in the quantum industry, especially among technology investors, is a result of its uniqueness in the sector. While trapped ions move around inside its competitors' computer, Quantum Art's technology cuts down on this flux, thereby enhancing the stability and precision of the computations. Laser beams "strum" the various ions and move them according to the calculation command "like a guitar is strummed," says Quantum Art cofounder and CEO Tal David. At the same time, the ions method also has disadvantages. First of all, the technology is more expensive, which complicates the transition from a small prototype to an industrial computer as big as a printer. Another difficulty lies in the processing speed and the engineering difficulty of greatly multiplying the number of qubits, but
