How One Paper Blew Up Bitcoin's Claim to Anonymity   By ZDNet, June 10, 2022

It has been a totem of the cryptocurrency community that the numeric addresses of Bitcoin and other wallets will protect the identity of those using them to buy and sell. 

A new paper, released this week by researchers at Baylor College of Medicine and Rice University, has shattered that presumed anonymity. Titled "Cooperation among an anonymous group, protected Bitcoin during failures of decentralization," the paper is now posted on the researchers' server.   

Lead researcher Alyssa Blackburn of Baylor and Rice, along with team-mates Christoph Huber, Yossi Eliaz, Muhammad S. Shamim, David Weisz, Goutham Seshadri, Kevin Kim, Shengqi Hang, and Erez Lieberman Aiden, used a technique called "address linking" to study the Bitcoin transactions in the first two years of its existence: January of 2009 to February of 2011.

Generating Photons for Comunications in Quantum Computing Systems

Precisely generating photons can be seen as a form of communication, and thus says this can then be beyond just computing.

Generating Photons for Communication in Quantum Computing System

MIT News,  Michaela Jarvis

Massachusetts Institute of Technology (MIT) researchers have developed a technique for inducing quantum bits (qubits) to generate photons to enable quantum processor communication, a key step in achieving interconnections for a modular quantum computing platform. The architecture features superconducting qubits connected to a microwave transmission line or waveguide, with quantum interconnects needed to link qubits at distant locations. Communication occurs in the waveguide as excitations stored within the qubits produce photon pairs, which are emitted into the waveguide and travel to two distant processing nodes, distributing their entanglement throughout a quantum network. Said MIT’s Bharath Kannan, the entanglement “can then be transferred into the processors for use in quantum communication or interconnection protocols."  ... '

Of consideration, could data be driven through systems like this?

Tor Just Launched the Easiest App Yet for Anonymous, Encrypted IM
THE ANONYMITY NETWORK Tor has long been the paranoid standard for privacy online, and the Tor Browser that runs on it remains the best way to use the web while revealing the least identifying data. Now the non-profit Tor Project has officially released another piece of software that could bring that same level of privacy to instant messaging: a seamless and simple app that both encrypts the content of IMs and also makes it very difficult for an eavesdropper to identify the person sending them.

On Thursday the Tor Project launched its first beta version of Tor Messenger, its long-in-the-works, open source instant messenger client. ... "
