Yes—but “between chips” is an imprecise shorthand. A 2025 experiment teleported a controlled-Z (CZ) gate between separate trapped-ion modules, while a 2026 neutral-atom experiment used logical teleportation within a reconfigurable processor. These experiments moved neither matter nor a gate-shaped signal through space: they used entanglement, measurements, classical communication and feed-forward to transfer a quantum operation’s effect.
What does “teleporting a logic gate” mean?
In quantum computing, teleportation is a protocol for transferring a quantum state or applying an operation remotely with the help of shared entanglement. The process uses measurements and classical information about their outcomes; the receiving system then applies a correction, often called feed-forward. The state or operation’s effect is reproduced at the destination, but the physical atoms or ions do not travel there.
That classical exchange matters: teleportation does not send information faster than light. It is also not the same as sending a conventional instruction over a cable. A remote quantum gate must be implemented through a coordinated protocol involving quantum resources at both ends and the necessary classical control.
What did the experiments actually demonstrate?
| Experiment | Hardware and separation | What was teleported | Measurements and error correction | Reported scale or result |
|---|---|---|---|---|
| Nature, 2026, Bluvstein et al. | Reconfigurable neutral-atom arrays; the work describes an architecture within a processor, not a link between conventional semiconductor chips. | Logical teleportations as part of a universal, error-corrected computing architecture. | Combines repeated quantum error correction, transversal gates, lattice surgery, three-dimensional [[15,1,3]] codes and mid-circuit qubit reuse. The source does not state a measurement-free protocol. | Arrays of up to 448 neutral atoms; protocols with dozens of logical qubits and hundreds of logical teleportations.

How did the trapped-ion gate work across modules?
The Nature 2025 experiment is the closest match to “teleporting a gate between chips,” though its hardware was separate trapped-ion modules rather than ordinary semiconductor chips. The modules first shared photonic entanglement through an optical network. Each module performed local operations and parity measurements; the control systems then exchanged the measurement results over a classical TTL link. Single-qubit feed-forward operations conditioned on those results completed the remote CZ gate.
#1 Best Overall
The reported average gate fidelity was 86.2(9)%. That number describes the measured teleported gate in this experiment; it is not a general accuracy figure for quantum computers, nor does it establish that the remote operation is error-free. The result demonstrates a way to coordinate a gate across distinct modules, not a mature, commercial chip-to-chip quantum interconnect.
What did the 2026 neutral-atom result add?
Bluvstein and colleagues used reconfigurable arrays of up to 448 neutral atoms to combine key components of a universal, fault-tolerant processing architecture. Rather than networking separate commercial processors, this work explored logical teleportation as an operation inside a single neutral-atom processor architecture.

Logical operations, not just physical-qubit demonstrations
The experiment brought together repeated quantum error correction, transversal gates, lattice surgery and three-dimensional [[15,1,3]] codes. In this setting, logical qubits are encoded across multiple physical qubits so that error-correction procedures can detect and manage faults. Teleportation provides a way to carry out logical operations within that encoded architecture.
Scale and error-correction evidence
The researchers report protocols involving dozens of logical qubits and hundreds of logical teleportations, enabled in part by mid-circuit qubit reuse. In a four-round characterization circuit, the distance-5 code showed 2.14(13)× lower error per round than the distance-3 code. The reported below-threshold behavior is limited to that characterization setting; it should not be read as proof that arbitrary long computations can already run reliably.

How is measurement-free logical teleportation different?
A separate 2026 study in Nature Communications demonstrated logical-state teleportation between two four-qubit error-detecting codes without mid-circuit measurements during algorithm execution. The team also ran Grover search on three logical qubits encoded in eight physical qubits.
This is a distinct result from both the neutral-atom architecture and the networked trapped-ion CZ gate. “Measurement-free” here is qualified: the source describes no mid-circuit measurements during algorithm execution, not an absence of measurements throughout preparation, control or readout.
Rank #4
Does this mean fault-tolerant quantum computers are here?
No. These are laboratory demonstrations of important architectural building blocks, not evidence that commercially available quantum computers have achieved full fault tolerance. The neutral-atom result shows several logical-computing ingredients working together at notable scale, alongside a bounded error-correction characterization. The trapped-ion result shows a teleported remote gate with measured fidelity below 100%. The measurement-free study demonstrates another logical-computation technique on a small encoded system.
For useful fault-tolerant computing, a system must sustain reliable logical operations and error correction across computations long and complex enough to matter. These results advance different parts of that challenge, but they do not establish that threshold-level performance and scaling are solved for general workloads.
