Development
QRL Zond Development
Several changes and improvements have been made to the execution node and related packages. One notable change is the unification of the pqaccounts and account packages into a single account package. Additionally, the pqcrypto package has undergone fixes and updates, including changes to the sign function.
The update also introduces a constant named DilithiumSignatureLength and makes various changes to transaction data and API to support Dilithium-based wallets. This includes added and initializing DilithiumWithdrawalPrefixByte, ZondAddressWithdrawalPrefixByte & DomainDilithiumToExecutionChange in config, fields which are used in the staking-deposit-cli for staking deposits and withdrawal.
This includes updates to the RPCTransaction API with new fields for PublicKey and Signature. Transaction marshalling has been updated to accommodate these new fields for Dilithium compatibility.
Several bug fixes and unit test updates have been implemented, and successful testing has been conducted for making and signing transactions from the CLI. Transaction Pool in the Execution Node has also been tested successfully, including fund transfers between Dilithium wallets.
The update covers progress in validator staking, including the exit of validators and withdrawal of balances. Non-required flags have been removed from the staking-deposit-cli, and various bug fixes and improvements have been made.

When QRL Zond Beta-Testnet?
It won’t be too much longer before everybody gets to try out the beta version of the QRL Zond beta-testnet network! The majority of the time is spent testing newly added functionality before it is made available to the team in order to ensure that appropriate documentation is created.
Generally:
- Node stability test ✅
- Testing of validator staking deposit and withdrawal ✅
- Testing of transfer of funds using dilithium wallet 🔎 <– in Progress
- Testing of contract deployment using dilithium wallet
- Testing of contract interaction using dilithium wallet
- Final cosmetic changes and basic documentation to install, run, stake and de-stake

Quantum News
Post-Quantum Cryptography Coalition Launches
On 26 Sep 2023: The data we're encrypting online today—from financial and personal identification information to military operations and intelligence data—could be quickly decrypted in the future by an adversary with access to a cryptographically relevant quantum computer. To drive progress toward broader understanding and public adoption of post-quantum cryptography (PQC) and the National Institute of Standards and Technology's (NIST) PQC algorithms, a community of technologists, researchers, and expert practitioners launched the PQC Coalition. Founding coalition members include IBM Quantum, Microsoft, MITRE, PQShield, SandboxAQ, and University of Waterloo. - mitre.org
Signal adds quantum-resistant encryption to its E2EE messaging protocol
On 25 Sep 2023: Signal has announced that it upgraded its end-to-end communication protocol to use quantum-resistant encryption keys to protect users from future attacks.
Signal explains that its "X3DH" (Extended Triple Diffie-Hellman) key agreement protocol has been upgraded to "PQXDH" (Post-Quantum Extended Diffie-Hellman), which incorporates quantum-resistant secret key generation mechanisms for Signal's end-to-end encryption (E2EE) specification. - bleepingcomputer.com
Physicists Create New Magnetic Material to Unleash Quantum Computing
On 18 Sep 2023: Researchers from the University of Texas, El Paso have developed a highly magnetic quantum computing material that retains its magnetism at room temperature. The material, which does not contain high-demand rare earth minerals, exhibits superparamagnetic behavior, making it a potential option for creating qubits, the basic unit of quantum information. By synthesizing the material in a sequential process, the researchers were able to produce a material 100 times more magnetic than pure iron. Further testing is needed, but this development offers promising potential for stable qubits and advancements in quantum computing. - sciencealert.com
When a Quantum Computer Is Able to Break Our Encryption, It Won't Be a Secret
On 13 Sep 2023: There is already more than enough reason to upgrade our communications systems to resist attacks from quantum computers as soon as possible. Even if completely unexpected attacks from a black-swan quantum computer are unlikely, attacks from known or suspected quantum computers would already be plenty bad enough. - rand.org
Laser Precision Qubit Control: Leap in Reliable Quantum Information Processing
On 11 Sep 2023: Researchers have pioneered a groundbreaking technique utilizing laser light to control individual qubits made of barium more robustly than any other method currently known. Reliably controlling qubits is a critical step towards actualizing functional quantum computers of the future. - scitechdaily.com
Chinese breakthrough a step towards scalable quantum computation: paper
On 10 Sep 2023: Chinese scientists have made a significant breakthrough in the development of practical processors for quantum computers. Previous studies were only able to entangle two atoms at a time, but the team was able to entangle eight and 10 ultracold atoms in two-dimensional blocks and one-dimensional chains respectively. - scmp.com
Checkmate! Quantum Computing Breakthrough Via Scalable Quantum Dot Chessboard
On 04 Sep 2023: Researchers at QuTech, a collaboration between the Delft University of Technology and TNO, have developed a new method for addressing quantum dots that could enable the operation of larger gate-defined quantum dot systems. The method uses a chessboard-like approach, where quantum dots are addressed using a combination of horizontal and vertical lines, similar to how chess pieces are addressed with letters and numbers. This approach reduces the number of control lines needed to address multiple qubits, potentially enabling the scaling up of quantum systems. The researchers also highlight the importance of improving the quality of qubits, with recent demonstrations showing a 99.992% fidelity. Additionally, the researchers discuss the potential application of quantum dot systems for quantum simulation, as they have shown that an array of germanium quantum dots can be used for rudimentary simulations of resonating valence bonds. The researchers are now focused on scaling up the chessboard circuits and exploring the possibility of interconnecting them to build even larger quantum circuits. - scitechdaily.com
