## Google's Quantum Leap
Google achieved a 40-fold reduction in quantum error rates using 'magic state cultivation' on its Willow processor, reaching 99.99% accuracy.

> Google ( GOOG ) ( GOOGL ) says it has demonstrated a new technique that reduces errors in a critical component of quantum computing by about 40-fold.
## Quantinuum's Error Record
Quantinuum's Helios quantum computer set a new error correction record with 99.9995% logical fidelity, surpassing previous industry benchmarks.

> In addition, Quantinuum ( QNT ) said its Helios quantum computer achieved a world record in error correction, with 99.9995% logical fidelity.
## Goldman Sachs Upgrades CoreWeave
Goldman Sachs upgraded CoreWeave to Buy, citing upside bias in recurring revenue per megawatt and internal rate of return.

> Among active stocks, last week's AI trade whipping boy CoreWeave ( CRWV ) is in focus after Goldman Sachs upgraded the stock to Buy from Neutral, albeit with a lower price target.
## Goldman Sachs Defensive Picks
Goldman Sachs recommends defensive, quality-growth stocks like TSN, CVS, SJM, KR, and CAH amid concerns over growth outlook deterioration.

> In other news of note, Goldman Sachs is recommending defensive stocks with quality-growth characteristics for investors worried that the recent deterioration in the growth outlook could lead to further downside.
## SpaceX Share Giveaway
Elon Musk plans to give every U.S. child one share of SpaceX, describing it as the 'first of many'.

> Elon Musk said he plans to give every child in the U.S. one share of SpaceX, describing the giveaway as the ' first of many .'
## SpaceX Share Value
One SpaceX share costs $150, enough for a child to buy GTA6 with cash to spare.

> At nearly $150, one share of SPCX is more than enough for each kid to cash it in and buy gta six, with cash to spare.
## Key takeaway

Google achieved 99.99% accuracy in quantum error correction with its Willow processor, a 40-fold reduction in error rates.
