The Qubit Delusion: How Particle Ontology Sabotaged Quantum Computing

In plain language

The paper set out to see whether the way researchers picture quantum bits—as tiny particles—has been holding back real progress in quantum computers. It found that most high‑profile claims are shaky: out of thirteen announced breakthroughs, only one (about 8%) was independently reproduced, while four (about 31%) were later challenged or qualified. The authors pointed out that error‑correction schemes still need thousands of physical qubits just to make one reliable logical qubit, far beyond today’s hardware. Because these structural and conceptual limits keep quantum computers from scaling up, the paper argues that abandoning the particle‑based view could open faster paths to useful machines. In practice, this means investors, policymakers, and engineers should rethink assumptions about qubits if they want the technology to move beyond laboratory demos.

What it claims

Numbers it reports

1. Capital lock-in : Venture capital fund lifecycles (typically 10 years), government program timelines, and corporate R&D budget inertia create structural barriers to exit.

2. In October 2019, Google announced "quantum supremacy" --- a 53-qubit processor, Sycamore, had performed a random circuit sampling task in 200 seconds that would, Google claimed, take the world's largest supercomputer 10,000 years to reproduce.

3. IBM's Eagle processor, with 127 qubits, had simulated the Ising model on a scale that strained classical methods.

4. Rigetti went public via SPAC at a $ 1.5 billion valuation in 2022; by 2024 its stock had declined over 90%.

   from 1. Introduction

5. Of the thirteen claims surveyed: 1 claim (8%) was independently replicated (Google's time crystal).

6. 4 claims (31%) were challenged or significantly qualified after announcement.

How it is done

1. The roadmaps project fault-tolerant machines in the 2030s, which would mean a roughly forty-year interval between Shor's algorithm (1994) --- the field's foundational existence proof --- and a working product.

   from 1. Introduction

2. While the Solovay -- Kitaev theorem guarantees that any unitary can be approximated by a sequence of gates from a universal set, the approximation incurs overhead.

   from 2.3 The Gate-as-Discrete-Operation Confusion

3. An alternative approach --- one that quantum computing has largely neglected --- would ask: can decoherence be the computation?

   from 2.4 The Decoherence-as-Enemy Confusion

4. The quantum computing timeline exhibits structural isomorphism with historical bubbles in several respects: Kernel of genuine science : Shor's algorithm (1994) and Grover's algorithm (1996) established legitimate theoretical results.

What would falsify it

1. The roadmaps project fault-tolerant machines in the 2030s, which would mean a roughly forty-year interval between Shor's algorithm (1994) --- the field's foundational existence proof --- and a working product.

   from 1. Introduction

2. The conclusions are falsifiable: Section 3 specifies the observations that would refute the central thesis.

   from 1. Introduction

3. Quantum computing institutions --- IBM, Google, IonQ, Rigetti, D-Wave, and the broader ecosystem of venture capital, government programs, and university labs --- face a structural trilemma: Scientific legitimacy requires publishing falsifiable claims, subjecting results to independent replication, and acknowledging negative results and limitations.

Where the claim stops

1. Even those timelines assume flawless execution of error-correction protocols that currently require thousands of physical qubits to encode a single logical qubit.

   from 1. Introduction

2. Every scientific model deploys scaffolds : arbitrary human conventions choice of basis, coordinate system, unit, epoch, gate set, qubit encoding --- that enable representation but do not inhere in the phenomenon represented.

   from 2.1 The Scaffold -- Invariant Distinction

3. But quantum reality does not evolve through discrete operations.
