Dealing with locality in QAOA
Mithilesh Kumar, Yusuf Tahir
Shallow-depth QAOA on sparse, high-diameter MaxCut instances faces a locality bottleneck: at depth \(p\), local observables can depend only on a bounded neighborhood of the circuit…

Assisted quantum teleportation
Mithilesh Kumar, Kaavya Iyer
Teleportation through a non-maximally entangled pair, e.g., , induces a noisy channel and cannot achieve deterministic unit-fidelity tr…

Congestion-free routing on quantum chips
Mithilesh Kumar, Yusuf Tahir, Varun Daiya +2
Limited connectivity makes nonlocal quantum gates expensive on near-neighbor hardware, where compilation typically relies on SWAP transport, inheriting both depth overhead and path…
