Commercial Pathways to Room-Temperature Topological Quantum Computation

In the paper's words

The realization of a room-temperature topological quantum computer using intrinsic quantum media is predicated on the successful engineering and validation of Fractional Chern Insulators (FCIs). This document presents a comprehensive, falsifiable research program to overcome the two primary barriers to this goal. The Temperature Gap—currently a two-orders-of-magnitude shortfall between the sub-meV energy scales of existing FCIs and the ~26 meV required for room-temperature operation—is addressed through a dual-engineering strategy.

The abstract, verbatim, and its opening sentence is the claim. Every line below is quoted from the text.

Numbers it reports

1. All verified experimental demonstrations of the FCI state occur at cryogenic temperatures, typically below 4 Kelvin (Park et al., 2023); (Lu et al., 2024); (Xie et al., 2025).

2. Sub-Thrust 1.2: Strain Engineering for Band Flattening The ratio $U/K$ can also be increased by quenching the kinetic energy $K$, which is achieved by making the electronic bands as flat as possible.

   from 4.1.2

How it is done

1. Concurrently, the Non-Abelian Statistics Gap—the lack of direct experimental proof that FCI quasiparticles possess non-commutative braiding statistics—is targeted with a definitive experimental protocol.

2. The most prevalent method involves the creation of a moiré superlattice by stacking two-dimensional materials with a precisely controlled relative twist angle or lattice mismatch (Park et al., 2023); (Lu et al., 2024).

3. Pathway 1: Moiré Superlattices in Transition Metal Dichalcogenides (TMDs) The moiré superlattice approach has been successfully demonstrated using transition metal dichalcogenides (TMDs) as the material platform.

   from 2.1

4. In one approach, an FCI state is induced in RMG by superimposing a moiré potential from a slightly misaligned substrate of hexagonal boron nitride (hBN) (Xie et al., 2025); (Lu et al., 2024).

What would falsify it

1. This document presents a comprehensive, falsifiable research program to overcome the two primary barriers to this goal.

   from Commercial

2. Falsifiable Hypothesis for Overcoming the Temperature Gap To address this critical challenge, a clear, testable hypothesis must be validated.

   from 3.1.1

3. The hypothesis would be falsified if, after exploring a wide parameter space of materials, dielectric environments, and strain conditions, the maximum achievable gap consistently saturates at a value significantly below 26 meV.

   from 3.1.1

Where the claim stops

1. However, the FCI state in twisted $\mathrm{Mo}\mathrm{Te}_{2}$ is not always the ground state; it exists in competition with other correlated phases, such as antiferromagnetism, requiring careful tuning of an external electric displacement field to selectively stabilize the desired topological order (Cai et al., 2025).

   from 2.1

2. Current FCI systems, however, exhibit topological gaps on the scale of a few Kelvin, corresponding to sub-meV energy scales, representing a gap of approximately two orders of magnitude that must be bridged (Park et al., 2023); (Lu et al., 2024).

   from 3.1

3. Science and Phase Competition Risks The proposed research thrusts are based on several core assumptions that may not hold true.
