Query: Measurement-only quantum computation with Majorana corner modes   Majorana modes, typically arising at the edges of one-dimensional topological
superconductors, are considered to be a promising candidate for encoding
nonlocal qubits in fault-tolerant quantum computation. Here we propose to
exploit the two-dimensional geometry of Majorana corner modes in second-order
topological superconductors to realize measurement-only quantum computation. In
particular, a periodically modulated topological superconducting system may
host eight Majorana corner modes, through which two logical qubits as well as
one ancilla qubit can be constructed and topologically protected gate
operations can be implemented by a series of Majorana parity measurements. The
measurements are achieved via Mach-Zehnder type interference in the conductance
of a semiconductor based topological superconductor. Our proposal represents a
scenario in which single- and two-qubit gate operations can be carried out in a
minimal setup that may provide a natural building block for Majorana-based
qubit architectures.
