Quantum Computers - Quantum Computing

Quantum computing relies on qubits, bits that are held in superposition and use quantum principles to complete calculations. The information captured or generated by a quantum system benefits from the ability of qubits to be in more than one physical state at a time (superposition), but there is information decay in capturing the state of the system. Quantum superposition, entanglement, and interference. One point that will be immediately relevant to the discussion is that quantum computers are not universally better than classical computers as a result. A quantum computer can do a certain task better than classical computers, perhaps one that is impossible to do in any reasonable timeframe with classical computers. Quantum technology approaches: superconducting, trapped ions, photonics, and silicon. 

IBM wants to build a 100,000-qubit quantum computer.  The company wants to make large-scale quantum computers a reality within just 10 years. IBM is set to release its most powerful quantum processor, the 1,121-qubit Condor chip, later this year. IBM to build 100K qubit quantum supercomputer with University of Tokyo and University of Chicago.

IBM intends to scale up its quantum computer to over 4,000 qubits by 2025 and beyond. IBM’s quantum roadmap essentially consists of two additional stages — the 1,121-qubit Condor and 1,386-qubit Flamingo processors in 2023 and 2024, respectively. We will introduce the 462-qubit “Flamingo” processor with a built-in quantum communication link, and then release a demonstration of this architecture by linking together at least three Flamingo processors into a 1,386-qubit system. IBM plans to hit the 4,000-qubit stage with its Kookaburra processor in 2025. Kookaburra will be a 1,386 qubit multi-chip processor with a quantum communication link. As a demonstration, we will connect three Kookaburra chips into a 4,158-qubit system connected by quantum communication for our users.

IBM watsonx Korea Quantum Computing (KQC) deal sealed installing an IBM Quantum System Two right in their Busan site. KQC is also diving into the world of Red Hat OpenShift AI for management and runtime, and they’re exploring the frontiers of generative AI technologies with the WatsonX platform. These are the tools that will fuel the next wave of innovation and efficiency in AI. Korean companies in finance, healthcare, and pharmaceuticals are joining the fray, eager to collaborate on research that leverages AI and quantum computing.

Quantum computers could soon connect over longer distances. For the technology to be used in future communications networks, researchers have developed a novel method of connecting quantum devices over great distances. Quantum repeaters are poised to become crucial in connecting distant quantum computers and enhancing security in communication networks in the future. The idea involves repeaters that transmit light that is telecom-ready thanks to one ion that has been inserted into a crystal. 

Key innovation in photonic components could transform supercomputing technology. Programmable photonic processors promise to outperform conventional supercomputers, offering faster, more efficient and massively parallel computing capabilities. The microelectromechanical systems (MEMS) at the heart of the new advance are tiny components that can interconvert optical, electronic, and mechanical changes to perform the variety of communication and mechanical functions needed by an integrated circuit.

PsiQuantum Has A Goal For Its Million Qubit Photonic Quantum Computer To Outperform Every Supercomputer On The Planet. PsiQuantum was founded on the belief that photonics was the right technology for building a fault tolerant quantum machine with a million qubits and that the proper approach was based on semiconductor manufacturing.

The Linux Foundation and its partners are working on cryptography for the post-quantum world

CRYSTALS-Kyber is designed for general encryption purposes, such as creating secure websites. 

CRYSTALS-Dilithium is designed to protect the digital signatures we use when signing documents remotely.

SPHINCS+ is also designed for digital signatures.

FALCON is another, less mature, algorithm for digital signatures.
