Improved Transversal Non-Clifford Gates from Cup Products
Louis Golowich, Itzhak Tamo, Guanyu Zhu
It is a major challenge in quantum fault-tolerance to obtain low-overhead protocols for performing non-Clifford gates. In this vein, we construct quantum codes with low-weight stab…
Quantum Codes with Transversal Gates and Sublinear -Stabilizers
Ohad Elishco, Itzhak Tamo
We construct asymmetric quantum CSS codes with transversal \(CCZ\) gates from algebraic expander codes \cite{KT26}. For every fixed \(m\ge 3\), our growing-alphabet codes have leng…
Breaking the bicycle frame: Coset-based quantum LDPC codes
Arda Aydin, Itzhak Tamo, Alexander Barg
Generalizing the construction of two-block group algebra (2BGA) codes, we introduce a family of two-block quantum LDPC codes constructed using the action of a group on the cosets o…
Codes with Large Minimum Distance in Product Codes: Explicit Constructions and Bounds
Amit Berman, Yaron Shany, Itzhak Tamo
Products of MDS codes are of major practical importance; for a recent example, they are used in Data Availability Sampling (DAS) in blockchain networks such as Celestia and as part…
Algebraic Expander Codes
Swastik Kopparty, Itzhak Tamo
Expander (Tanner) codes combine sparse graphs with local constraints, enabling linear-time decoding and asymptotically good distance--rate tradeoffs. A standard constraint-counting…
