NTT Scientists Say They Have New Way to Verify Quantum Advantage

NTT Research announced that a scientist from its Cryptography and Information Security (CIS) Lab and a colleague from the NTT Social Informatics Laboratories (SIL) have written a pathbreaking paper on quantum advantage. The paper was selected to be presented at the annual IEEE Symposium on Foundations of Computer Science (FOCS), which is taking place Oct. 31–Nov. 3 in Denver. The co-authors of the paper, titled “Verifiable Quantum Advantage without Structure,” are Dr. Takashi Yamakawa, distinguished researcher at NTT SIL and Dr. Mark Zhandry, senior scientist in the NTT Research CIS Lab.

NTT envisions a “greener” IoT sensor

NTT Research has created a circuit and a battery connected by wires made of carbon tubes as opposed to copper. Copper is both rare and harmful to the environment in large quantities, whereas this battery is completely recyclable and uses chemicals found in fertilizer to power the transistor. The resulting transistors are very low-frequency devices that don’t even achieve a kilohertz of performance. (Chip performance is measured by frequency, with today’s high-performing chips reaching frequencies of multiple gigahertz.) These transistors can’t even generate enough performance to send out a radio signal. Which, by the way, is the next goal of the research team.

Cryptography: A new kind of proof system

A recent paper by Dr Brent Waters, NTT Research Cryptography & Information Security (CIS) Lab director and Dr David Wu, an assistant professor at University of Texas at Austin, is significant as it develops new techniques for communications and the proof system model. Proof systems are a useful building block for authentication systems. They consist of a proving party and a verifying party, where the prover is trying to convince the verifier that a ‘statement’ is true. Typically, the verifier relies on the prover to provide a witness. Cryptography: A new kind of proof system | ITWeb

Takashi Goto has been appointed as Head of its Technology Promotion Team, a group set up to help productize well-developed research concepts. Goto was previously a director in the NTT R&D Planning Department and before that, a senior manager and senior research engineer at the NTT Information Network Laboratory Group. He joined NTT Research on July 1, 2022, succeeding Dr Kei Karasawa, who has taken an executive position at NTT R&D in Tokyo. Goto will join the executive team at NTT Research, where he will be responsible for exploring the market potential for technologies under development at NTT Research, as well as NTT R&D. One of the first targets for commercialization is attribute-based encryption (ABE), a form of cryptography that allows for sharing data while preserving the data owner’s privacy.
