In pursuit of large-scale fault-tolerant quantum computation, quantum low-density parity-check (LPDC) codes have been established as promising candidates for low-overhead memory when compared to conventional approaches based on surface codes. Performing fault-tolerant logical computation on QLDPC memory, however, has been a long standing challenge in theory and in practice. In this work, we propose a new primitive, which we call an $\textit{extractor system}$, that can augment any QLDPC memory into a computational block well-suited for Pauli-based computation. In particular, any logical Pauli operator supported on the memory can be fault-tolerantly measured in one logical cycle, consisting of $O(d)$ physical syndrome measurement cycles, without rearranging qubit connectivity. We further propose a fixed-connectivity, LDPC architecture built by connecting many extractor-augmented computational (EAC) blocks with bridge systems. When combined with any user-defined source of high fidelity $|T\rangle$ states, our architecture can implement universal quantum circuits via parallel logical measurements, such that all single-block Clifford gates are compiled away. The size of an extractor on an $n$ qubit code is $\tilde{O}(n)$, where the precise overhead has immense room for practical optimizations.

The LPDC consequently suspended Ocha Ulegede, Esq, from legal practice for two years with effect from the date of delivery of the judgment. The post Zaki Biam killing: LPDC suspends Gadzama, one other over FG’s N8bn settlement appeared first on Tribune Online.

The five-year ban slammed on a former Attorney General of Imo State, COC Akallisa by the Legal Practitioners Disciplinary Committee (LPDC) has been lifted. The ban was lifted by the Supreme Court of Nigeria following a barrage of suits against the committee. Recall that a six-member panel of the LPDC banned Akolisa from legal practice for five years in July 2021 over his conduct.

A coalition of civil society organisations operating under the Civil Society Groups of Good Governance has rejected claims that the Legal Practitioners Disciplinary Committee dismissed allegations of certificate fraud against the Deputy Speaker of the House of Representatives, Benjamin Okezie Kalu. In a statement released in Abuja on Thursday, the president of the coalition, Chief Dominic Ogakwu, described reports suggesting that the deputy speaker had been cleared as misleading.
