The quantum computer maker boosted the price and number of shares it will issue on the New York Stock Exchange ahead of its public debut on Thursday, indicating higher-than-anticipated demand. Quantum computers are a nascent technology that promise to solve problems current machines can’t,

Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines.

The quantum computing trade has shifted from a speculative bet to an identifiable, investable theme, and the three exchange-traded funds that best capture it each take a different angle on the same transition.

Digital secrets are protected by encryption, which converts meaningful data into an unintelligible form. If quantum computers could unscramble current encryption, they could expose highly sensitive data. Useful, perhaps, for nation states tracking terror cells or spying on strategic competitors – but bad news for everyone else.

Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those promises could be many years away

For six years, 48 qubits was the wall. No classical supercomputer on Earth could perform a universal, exact simulation of a quantum machine beyond that threshold, a limit set in 2019 by Japan’s now-retired K computer.

OQC builds quantum chips by placing transmon qubits atop a thin layer of sapphire. According to the company, its engineers create the qubits using photolithography techniques and an electron beam. The other side of the sapphire substrate hosts devices called resonators that are responsible for extracting calculation results from qubits.

Quantum Machines (QM), the global leader in hybrid quantum-classical control solutions, today announced that it has successfully operated Rigetti Computing’s commercially available Novera™ superconducting quantum processing unit using QM’s OPX1000 hardware and QUAlibrate software,

Quantum Machines has raised $170 million in funding to accelerate adoption of quantum computing and improve its advanced quantum control solutions. The third round of funding brings the company’s capital raised to date to $280 million. The investment ...
