# What is the maximum separation between two entangled qubits that has been achieved experimentally?

Considering two entangled flying qubits, as far as I know, there is no physical limit for separating them without losing quantum information.

## Question

1. What is the actual record in such distance using photons? I have found a previous record in 143 km (Physicists break quantum teleportation distance)

2. What about using solid-state based qubits?

3. Can this suppose a limitation when constructing a solid-state quantum computer?
